In this method, self refers to the button that called it, not the parent
window.

def splash_done(self):
    print "Clicked OK"
    self.destroy()

All you have to do is destory the button's master (the parent window).

def splash_done(self):
    print "Clicked OK"
    self.master.destroy()


Cool? Cool.
