Writing GUI(Windows Forms) using Python?

Question

How do people code Windows forms through python? Does one have to use some kind of API or through C# in Visual Studio? Example: I would like to write a small form calculator with buttons using python, could you suggest any articles/books to read dedicated to this topic?
Thanks in advance ;)

you can also use libraries such as tkinter (built-in) wxPython and pygame. they have classes and functions to help create guis and have better documentation than iron python
