pretty much what wayne suggested. you need to put the btnStat variable
into your instance's namespace, hence self.btnStat = ... instead of
just btnStat whose namemapping will disappear when __init__()
completes even though the object still exists -- it's just an extra
reference held somewhere else.
by stashing it away into the instance('s dictionary), you'll be able
to access it again in the btnStatclick() callback.
