Nice. If you wanted to edit the tutorial materials or add chapters to
the main GTK manual, feel free. 
http://developer.gnome.org/doc/API/2.0/gtk/index.html
should really have tutorial stuff in the "GTK+ Overview" part, 
and an expanded "Common Questions"
Personally I'd like to see the GTK+ tutorial updated and merged 
in to the main manual.

Comments on the tutorial -

 - it seems to imply that on_delete is necessary to get the window 
   destroyed; this isn't the case, if you don't connect to
   delete_event at all, it's equivalent to connecting a handler 
   that simply returns FALSE. i.e. destroy happens automatically.

 - set_default_icon_from_file() will already just print a warning to
   stderr if the icon is missing I'm pretty sure, if you pass NULL for
   the GError**; so you could omit the error handling here and simply
   pass NULL, for the same effect.

 - could use gtk_widget_show_all() on the window instead of 
   showing the label separately

 - few programs seem to bother with #ifdef HAVE_CONFIG_H

 - there's no need to include glib.h separately, as gtk/gtk.h 
   sucks it in
