[pygtk] Newbie question

[Geert Geurts]

Hello, 
I'm a newbie trying to get to know pygtk/gtk so my questions might seem
stupid...
Sorry for that.

I'm trying to write a CDrip application using glade/pygtk. I'm now able
to write a program making a gui where you can write the artist album
info, and the cd is being ripped when you click the button. But I want
it to also show a progress window but this second window is shown as
soon you start the application altough the second window is in a
seperate  class and is not initialized before a button click.
How come this window is shown before initialisation and how can I
control this behaviour?

Greetings,
Geert
