Tic-Tac-Toe with GUI in Python

This is a classic Tic-Tac-Toe game with GUI made in Python.
I wanted to make a game with GUI (Interface with Graphics) and AI (Artificial Intelligence - Meaning that the user's opponent is the computer itself and not a human being) so I thought:

"What can be simpler than Tic-Tac-Toe??"

You can download and try it for yourself HERE.

Instructions:
1)Download the .zip file
2)Unzip/Extract it
3)In folder 'dist' run "tic-tac-toe.exe"

Have fun ;).
