Ha I know why you want to make that... because it looks better and you
can customize the big buttons. I just did that, and it's easy. Here's
how:

- Set each button to be a toggle button
- Create a global GtkWidget pointer for each of the buttons
- In the callback for the toggle button set the other buttons to go
"unpressed" using their global pointers.
- Here you go!

The trick is to set the pointer to button as a global instead of one
inside main(), so you can change the button's state from within other
callback functions.

Bye
