Pygame is a good choice for creating GUI and game dev.
Install:
Windows:
pip install pygame

python3 -m pip install -U pygame --user

import pygame

# Pygame basics
# Type pip install pygame on your cmd or powershell
# If your on mac on your terminal type pip3 install pygame

# Why pip3 on mac?

"""
Pip 3 on mac because mac already has Python 2 installed so if you type pip on your terminal in mac
it will install it for python 2 so that is why you have to type in pip3 instead of pip on mac"""

"""
Pygame is a module that you need to install on your cmd or terminal or powershell 
and is used for making 2D arcade games"""
