Lost in choosing how to make an graphic interface

[TheGuyUnknown]

Hello everybody, as a novice in python coding (i've been on C++ for the past few years), i would like to create a program that can simulate a trajectory of a ball after i choosed the shooting angle and speed of shooting. However, i am completely lost among all the libraries such as Tkinter or Pyqt for instance. I do not now what to choose or to do to make this simulation something graphic.
Any help is appreciated !
Thanks !

What did you use in c++ ?

Could always use a library that matches.

I recommend you checkout vpython.

What is your interest in making this? Gaming? GUI? A one time program or a leap to more complex? 2d or 3d? That might help us to select the correct library to head you towards.
