I think you meant to reply to the list, not to me.  I couldn't answer  
the win32 question.

We use Gtk2::Ex for pure-perl add-on modules.  Apps go in the most  
appropriate namespace for what each app does.

Gdk represents a window manager kill as "delete-event",  Return a true  
value from your handler to stop propagation.

   # warning, untested code typed straight into an email
   $window->signal_connect (delete_event => sub {
       my ($win, $event) = @_;
       my $answer = 0;
       if (document_is_dirty ($win)) {
           my $dlg = Gtk2::MessageDialog->new ($win, [], 'question',  
'yes-no',
                                               "Are you sure you want  
to quit?");
           $answer = ('yes' eq $dlg->run);
           $dlg->destroy;
       }
       return $answer;
   });

You get bonus points for the minimal extra work to use "Quit" and  
"Don't Quit" for the buttons instead of "Yes" and "No".

gtk_widget_set_size_request() effectively sets the widget's minimum  
size, as you have observed.  The fix is to use  
gtk_window_set_default_size() on the toplevel, and do NOT set the size  
request on the drawing area widget.

    $toplevel_window->set_default_size ($width_pixels, $height_pixels);

That's a common thing i've seen in other apps.  Sounds nice.

Create a description page to which we can link, and we'd be happy to.   
You know, what does the app do, what does it look like, what do you  
need --- more than just a tarball in a directory.  ;-)
