Newbie wxPython questions.

Instead of self.Close(), try parent.Close()

The self.Close() is closing self, which is a panel.  The panel's parent
is the frame.  This will let you keep the button on the frame, which
eliminates the spacing problem.

I'm not gonna test it, cuz the darn lines wrap and make it difficult to
copy your code, but it should go :)
