Tkinter guide?

[Serafim]

Then why not use one of the wrappers around tkinter like e.g. PySimpleGUI. I also thought tkinter, and other GUI stuff was complicated so when asked to create a simple Japanese character learning application I used PySimpleGUI with quite rapid success.
Generally speaking, GUI programming is a lot of work as you have to manage all the details of a window and its components + connect all those details to code that will perform whatever action is to be taken. Regardless of language it is not a simple task.
