Try Test.redraw(), the redraw method was made specifically for this 
purpose. The method is defined in widget.py

     def redraw(self):
         """Force an immediate redraw without waiting for an event 
handler to finish."""
         self.Refresh()
         self.Update()

Actually, I think using a timer is the right way to reenable the 
button. You may also need to consider calling SafeYield() depending on 
how responsive you want the UI to be during your processing. There are 
many samples that do long processing, so take a look at them for more 
examples.
