Building Python GUIs is easy with Embarcadero’s RAD Studio. You can use either Delphi or C++Builder to build the GUI side of the app. Integrating Python into native Windows GUI apps produced by RAD Studio is easy, and they look great. RAD Studio (Delphi and C++Builder) provides many powerful features like REST clients, servers, web servers, and more. However, this is a great place to start if you have an existing Python app or want to add Python to your existing Delphi app to access Python libraries or provide scripting for users.
This post will discuss many posts on PythonGUI.org that will teach you how to build powerful Windows GUI apps integrated with Python. These posts cover Python REST servers, a Python web server, map, filter, and reduce functions, python decorators, partial functions, code introspection, and closures. Take a look!
