If you instantiated your Gtk::Window object on the stack within scope of 
a function call, such as in a main() function:

int main (int argc, char *argv[])
{
   Gtk::Main kit(argc,argv);
   Gtk::Window win;

   kit.run(win);

   return 0;
}

the Gtk::Window win will call its own destructor when the main() 
function goes out of scope.  If, however, you declared your Gtk::Window 
as a pointer and instantiated it using "new":

int main (int argc, char *argv[])
{
   Gtk::Main kit(argc,argv);
   Gtk::Window *win = new Gtk::Window;

   kit.run(*win);

   delete win;
   return 0;
}

You would be obliged to delete that object prior to the function going  
out of scope as shown above.   I hope this helps.
