Try something like this:
gboolean
resize_window_on_idle (gpointer data)
{
gtk_window_resize (GTK_WINDOW(data), ... , ...);
return FALSE;
}
// ...
gtk_widget_show_all (window);
g_idle_add (resize_window_on_idle, (gpointer) window);
The window may flicker a bit ( I mean the size change will be visible by the
user ) but it will work.
You can also pass a composite structure with the window, width and height to
g_idle_add if you want.

This may do the trick as well.

If you mean gtk_widget_size_request yes there will be differences but
not what you want. This will set the preferred size of your window so
you won't be able to shrink it.
