Welcome to the wonderful world of Python hacking.

1) you can disable the button (at the start of the command bound to the button)
or,

2) in the same place, you can use configure to change the button's command
binding to a routine that does nothing and just returns

Don't forget to reverse whatever changes you have
made when the user closes the window, or it will
be a "one-shot" system.
