I tried all of the above, but didn't get it to work. Would it be
possible for you to get the test program below to work (which means
if you press the button, resize the window with your mouse, press
the button again and get the main window be resized to a width of
200 and a height of 100)?
This would be a great help!

Here is the test program:
#include <gtk/gtk.h>

void hello( GtkWidget *widget, GtkWidget *win)
{
    gtk_widget_set_usize(win, 200, 100);
}

void destroy( GtkWidget *widget,
              gpointer   data )
{
    gtk_main_quit();
}

int main( int   argc,
          char *argv[] )
{
    GtkWidget *window;
    GtkWidget *button;
    gtk_init(&argc, &argv);
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_signal_connect (GTK_OBJECT (window), "destroy",
                        GTK_SIGNAL_FUNC (destroy), NULL);
    gtk_main_quit();
}

int main( int   argc,
          char *argv[] )
{
    GtkWidget *window;
    GtkWidget *button;
    gtk_init(&argc, &argv);
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_signal_connect (GTK_OBJECT (window), "destroy",
                        GTK_SIGNAL_FUNC (destroy), NULL);
    gtk_container_set_border_width (GTK_CONTAINER (window), 10);
    button = gtk_button_new_with_label ("Hello World");
    gtk_signal_connect (GTK_OBJECT (button), "clicked",
                        GTK_SIGNAL_FUNC (hello), (gpointer)window);
    gtk_container_add (GTK_CONTAINER (window), button);
    gtk_widget_show (button);
    gtk_widget_show (window);
    gtk_main ();

    return(0);
}
