Program a Raspberry PI as a simple scoreboard for Shuffleboard.

I want to use my Raspberry Pi and a TV-screen as a Shuffleboard scoreboard. I have three physical buttons, when i press button1 it should add a point for team number1, when i press button3 it should add a point for team number2 and when i press button2 it should reset both counters. They are connected like this and ive used gpiozero: button1 = Button(2), button2 = Button(3), button3 = Button(4). I will also need a GUI with a background photo and the score for each team.
