There should be a set_label function, as it's provided by the grandparent 
GtkButton widget. I get the feeling you're using Python bindings? Fine choice 
of language, but not a set of GTK bindings I'm familiar with (I mostly use

Well, you most certainly don't want to hook up anything with a gtk.main_quit() 
call, because that will close your application. Just because the file 
selection code sits in its own module doesn't make it a different GTK 
instance. What you should do, and probably in the file selection module not 
the main program, is connect a simple "hide" call to the cancel button. For 

class MyFileWidget :
   def Setup ( self, other args ) :
       <do stuff>
       self.cancel_button.connect("clicked",lambda w: self.give_up())

   def give_up ( self, widget ) :

You don't actually need to destroy the file selector - you could keep it 
around for later, or allow the instance to be deleted by Python by going out 
of scope.

I don't have answers for the other two questions right now, sorry.
