I think what you want is:

void gtk_window_set_policy (GtkWindow           *window,
                            gint                 allow_shrink,
                            gint                 allow_grow,
                            gint                 auto_shrink);

With autoshrink=TRUE. This means that the window should
always be exactly the size requested by its children -
normally GTK+ does not shrink a window back down if
its children get smaller.
