Here's a general design pattern that may seem like more work, but
actually keeps your code cleaner and easier to manage. First, buttons
should never do very much except let the form know that they've been
clicked. So your button code should read:
def onHit(self, evt):
self.Form.createSpreadsheet()
That's it. Now add that method to the form, and since it needs data
from the bizobj, get the data, and do whatever formatting and
outputting of the data that you need.

That's pretty self-expanatory. Since the code is executing as part of
the button, 'self' refers to the button.
