A GtkWindow is also a GtkWidget, and looking at the reference
documentation
http://library.gnome.org/devel/gtk/stable/GtkWidget.html#gtk-widget-destroy you can use gtk_widget_destroy() 
on a window to decrease its reference count by one. When this reference count reaches 0, the widget is 
finalized and its resources returned to the system. This technique is applicable to all objects that inherit 
from GtkWidget.

This reference-counting system is based on GObject, which has some nice
reference documentation at
http://library.gnome.org/devel/gobject/unstable/gobject-memory.html if
you want to read further.
