Create GUI Applications with Python & Qt — PySide6 Edition

Want to create GUI applications with Python? Here is everything you need to go from your first window to complete apps.

In this book I'll show you how to create your own GUI applications in Python using PySide6. Starting with a basic window on your desktop, we'll work step by step towards building professional apps you can be proud of.

I've been developing Python desktop applications for 8 years using Qt. It's a great way to create professional and portable apps with Python. But when you're starting out, it can be tricky to know where to start. In this book I've collected everything I wish I'd known when I started & the most useful things I've learnt since.

In 2021 the book was updated for Qt6. You will receive the PySide6 edition of the book and all future updates.
