Build a GUI App in 30 Days: A Practical PyQt6 Master Plan

Build a GUI App in 30 Days: A Practical PyQt6 Master Plan

Building desktop applications often feels intimidating—especially when the goal is a polished, responsive, and professional user interface. Fortunately, Python combined with the Qt framework makes modern desktop development far more approachable than many developers expect.

PyQt6, a set of Python bindings for the Qt framework, allows you to build fast, cross-platform GUI applications with a native look and feel on Windows, macOS, and Linux.

This 30-day master plan is designed to take you from zero to a fully functional User Account Maintenance application—the kind of internal tool commonly used to manage users in systems like Active Directory (AD) or enterprise platforms. Along the way, you’ll learn not just how to build a GUI, but how to structure it correctly for real-world use.

Each day focuses on a manageable, practical goal that builds on the previous one.


What You’ll Build

By the end of this challenge, you’ll have created a desktop application that can:

  • Search and display user accounts
  • Create, edit, and delete users
  • Persist data locally using SQLite
  • Optionally integrate with Active Directory / LDAP
  • Remain responsive during long-running operations
  • Be packaged as a standalone executable and installer

Just as importantly, you’ll understand why the application is structured the way it is.

(Printable, one page, real blank checkboxes.)


Week 1: PyQt6 Fundamentals & UI Design

Day 1 – Environment Setup

Create a Python virtual environment, install PyQt6, and launch a minimal QMainWindow.

Outcome: A window appears without errors.


Day 2 – Layouts & Widgets

Work with QLabel, QLineEdit, QPushButton, and layout managers such as QHBoxLayout and QVBoxLayout.

Outcome: A responsive layout that resizes correctly.


Day 3 – Qt Designer

Design a form visually using Qt Designer and save it as a .ui file.

Outcome: A usable UI created without manual layout code.


Day 4 – UI Loading

Load the .ui file into Python using uic.loadUi().

Outcome: The Designer-built UI loads correctly at runtime.


Day 5 – Signals & Slots

Connect UI events (button clicks, text changes) to Python methods.

Outcome: UI actions trigger application logic.


Day 6 – Main Window

Design the primary application window with a search bar, results view, and action buttons.

Outcome: Core interface layout completed.


Day 7 – Dialogs

Create modal dialogs for creating and editing users.

Outcome: Dialogs open, close, and return user input.


Week 2: Data Handling & Application Structure

Day 8 – Model/View Architecture

Use QStandardItemModel with QTableView to separate data from presentation.

Outcome: Table view displays structured data.


Day 9 – Create User

Retrieve data from the dialog and add it to the model.

Outcome: New users appear immediately in the UI.


Day 10 – Edit User

Detect the selected row and update existing user data.

Outcome: Selected users can be edited safely.


Day 11 – Mock Backend

Introduce a data access layer to decouple UI from logic.

Outcome: UI calls backend methods instead of manipulating data directly.


Day 12 – SQLite Backend

Persist user data using SQLite.

Outcome: Data persists across application restarts.


Day 13 – Search

Implement filtering using database queries or a proxy model.

Outcome: Search bar dynamically filters results.


Day 14 – Menus & Toolbars

Add a menu bar and toolbar with reusable actions.

Outcome: Multiple navigation paths function consistently.


Week 3: Enterprise Integration & Robustness

Day 15 – LDAP Concepts

Learn LDAP fundamentals and perform read-only directory searches.

Outcome: LDAP search script runs successfully.


Day 16 – LDAP Integration

Integrate a live LDAP/AD backend in read-only mode.

Outcome: Directory users populate the table view.


Day 17 – AD Write Operations

Safely create and modify users in a test directory environment.

Outcome: Controlled write operations verified.


Day 18 – Threading

Move long-running operations off the UI thread using QThread.

Outcome: UI remains responsive during searches.


Day 19 – User Feedback

Add status messages and progress indicators.

Outcome: Users receive clear feedback during operations.


Day 20 – Error Handling

Add robust error handling and logging.

Outcome: Errors are logged and user-friendly messages are shown.


Day 21 – Application Settings

Persist window geometry and preferences using QSettings.

Outcome: Application restores previous state on launch.


Week 4: Polishing & Deployment

Day 22 – Styling

Customize the application appearance using Qt Style Sheets (QSS).

Outcome: Application has a consistent visual theme.


Day 23 – Icons & UX

Add icons and small UX improvements.

Outcome: UI feels more professional and intuitive.


Day 24 – Custom Widgets

Create reusable widgets by subclassing QWidget.

Outcome: Cleaner, reusable UI components.


Day 25 – Testing

Write tests using pytest-qt for logic and UI behavior.

Outcome: Automated tests validate application behavior.


Day 26 – Packaging

Bundle the application using PyInstaller.

Outcome: Standalone executable created.


Day 27 – Validation

Test the application on a system without Python installed.

Outcome: Application runs successfully.


Day 28 – Installer

Create a professional installer using Inno Setup or NSIS.

Outcome: Installer completes successfully.


Day 29 – Cleanup

Refactor code, add documentation, and write a README.

Outcome: Project is maintainable and hand-off ready.


Day 30 – Review

Review what you’ve learned and plan your next project.

Outcome: Clear direction for continued learning.


Final Thoughts

In 30 days, you’ve progressed from a blank Python file to a fully structured, professional desktop application. More importantly, you’ve learned patterns and practices that transfer directly to real-world projects.

If you can build this application, you can build almost any internal desktop tool your organization needs.
