Hmmm, here you are creating a GtkWindow: 
>     /* create window, set default height and width to 200 pixels */
>     window = g_object_new(GTK_TYPE_WINDOW,
>                           "default-height", 640,
>                           "default-width", 480,
>                           "border-width", 12,
>                           "title", "Kiosk",
>                           NULL);

And now you create a GtkImage:
>     image = g_object_new(GTK_TYPE_IMAGE, "file", "Background.jpg", NULL);

And now you are calling function that takes GdkWindow & GdkPixmap arguments:
>     gdk_window_set_back_pixmap((GdkWindow *)window, (GdkPixmap *)image, FALSE);

I'd say that your not out of the woods yet ;-p

You'll find the GdkWindow your looking for hanging around in 
GTK_WIDGET(widget)->window once that window is realized
(you can g_signal_connect_after (... "realize".. ) if you need to be
notified, otherwise just calling gtk_widget_realize (widget) first
might work).

You should browse the API docs in GDK (specificly the windows & pixmap
& pixbuf sections), to find out the most suitable way to aquire a GdkPixmap;
Note that a GdkPixmap in "X" terms in synonymous to Pixmap (and offscreen
server side drawable).

Cheers,
