Okay I'm mad at myself for forgetting this:

if __name__ == "__main__":
	helloWorld = HelloWorld()
	gtk.main()

When I add that, a new problem arises: the terminal floods with:
  File "./helloWorld.py", line 12, in setWindow
    self.window = window
  File "./helloWorld.py", line 12, in setWindow
    self.window = window
  File "./helloWorld.py", line 12, in setWindow
    self.window = window
ad infinitum
