window isn't guaranteed to exist until the object is realized. It may
exist, but there is no guarantee.

You can either force realize, or do your drawing at a later time, after
realization. For drawing areas the easiest thing is to override
configure_event_impl. For buttons you aren't really meant to be accessing
the window, I don't think.

Why not just add a child to the button, such as a drawing area or pixmap
or label or whatever you want?
