What in particular is not working?

One thing that is not quite clear from what I referred you to is that
you must pass GTK_TRUE to gtk_widget_set_app_paintable.

Other than that the calls should be pretty self explanatory. I tested
the method described using PyGTK, and it worked fine.

Here is a hint, as a C snippet, based on the Python code I tried:

GError *err;
GtkWindow *win;
GdkPixbuf *pixbuf;
GdkPixmap *pixmap;

pixbuf = gdk_pixbuf_new_from_file("image.png", &err);
gdk_pixbuf_render_pixmap_and_mask(pixbuf, &pixmap, NULL, 0);
g_object_unref(pixbuf);

win = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_widget_set_app_paintable(GTK_WIDGET(win), GTK_TRUE);
gtk_widget_realize(GTK_WIDGET(win));
gdk_window_set_back_pixmap(window->window, pixmap, GTK_FALSE);

g_object_unref(pixmap);

# A literal PyGTK equivalent

pixbuf = gtk.gdk.pixbuf_new_from_file('image.png')
pixmap = pb.render_pixmap_and_mask()
del pixbuf

win = gtk.Window()
win.set_app_paintable(gtk.TRUE)
win.realize()
win.window.set_back_pixmap(pixmap, gtk.FALSE)
del pixmap
