I can't help with the performance problem, but you don't really need a generator for your x-values. This works:

def move_panel(self, evt):
    for i in xrange(400):
        x = 200-abs(i-200)
        self.square.SetPosition((x, 30))
        time.sleep(0.005)

The generator *does* make for clearer code, though!
