btnStat isn't defined here. I think you should be declaring a self.btnStat
in the __init__ method (which I usually put as the first function in my
class - I'm honestly not sure if it makes a difference), and calling
self.btnStat

Unlike C/C++, python is explicit when dealing with members of the class. I'm
not sure if anything is implied when it comes to namespaces, but I'm pretty
sure it's all gotta be specific.

HTH,
