[Devember 2021] GTK4 Connect 4 app using radio button and rust

Attempting to do my first Devember. Purely for fun / learning purposes.
Please guide me if I am messing up.

I saw this fun video on twitter today,
Connect four using radio buttons

I want to see if I can build a gtk-4 + rust version of this.

This project will be me trying to learn basics of rust, gtk4 and trying to make an app.

What I know :-

What is my plan
