First of all, why on earth are you using a for loop!?  Either user a timeout or an idle, to increment the 
count.  And when the button is clicked, stop it.

Any loop that takes more than a fraction of a second to run is bad, evil, and probably just plain wrong.  GTK 
is an event driven toolkit.

Store the id returned when you create the timeout or idler, and use it in the button callback to remove the 
event so it doesn't get called anymore.

Always keep in mind that GTK is an event driven toolkit, surrounding an engine that creates events.  Any time 
your program needs to sit and wait for anything, you're probably doing something wrong.  And if your program 
is doing something non-event-driven (like sitting in a for loop), and expecting to do something when 
something event-ish happens (like clicking on a button), that's bad also -- mixing event driven and 
non-event-driven tequniques is bound to cause trouble.
