Don't write an infinite loop :-)

Something like this might help:

	while (condition) {
		/* Do something */
		processEvents();
	}

And make sure that condition changes from true to false when the loop must be 
broken.

Note that the "Do something" part should be fast so that the GUI doesn't 
block.
