yes, structures are allocated for each class of object

either when you delete it (the elegant way) 
or when the application is closed, by the OS (the easiest way),

gtk_widget_destroy (window);

This function is supposed to free the window widget AND
all the gdk/gtk objects linked to window, at any nested level,
as buttons, etc.

gtk_main_quit ();

will free gd/gtk general resources, that
were not specifically required by the user,

How you handle exit operations depends of your 
own app, of course, but I think you should really try 
to free memory yourself, instead of waiting for the 
OS cleanup.
