Abstract PyQt6 is a set of Python bindings for the Qt6 application framework, enabling developers to create cross-platform desktop applications with native look and feel. This paper provides a structured tutorial on PyQt6, covering installation, fundamental concepts (signals, slots, widgets, layouts), event handling, and practical application development. By the end, readers will be able to build functional GUI applications. 1. Introduction Qt is a powerful C++ framework for GUI development. PyQt6, developed by Riverbank Computing, allows Python programmers to harness Qt’s capabilities. Compared to Tkinter, PyQt6 offers more widgets, better styling (QSS), and advanced features like OpenGL integration, multimedia, and networking. # Signals self

This paper provides a ready-to-use tutorial for beginners and intermediate Python developers. Each code block is executable and demonstrates a standalone concept. Compared to Tkinter, PyQt6 offers more widgets, better
