No, this should be fine. Something is broken in your program :-) 

This code works for me:

-- 
#include <gtk/gtk.h>

static void
button_clicked( GtkWidget *button, GtkWidget *draw )
{
        static int size = 20;

        gtk_drawing_area_size( GTK_DRAWING_AREA( draw ), size, size );

        size += 20;
}

int
main( int argc, char **argv )
{
        GtkWidget *window;
        GtkWidget *button;
        GtkWidget *draw;

        gtk_set_locale();
        gtk_init( &argc, &argv );

        draw = gtk_drawing_area_new();
        button = gtk_button_new();
        gtk_container_add( GTK_CONTAINER( button ), draw );
        gtk_signal_connect( GTK_OBJECT( button ), "clicked",
                GTK_SIGNAL_FUNC( button_clicked ), draw );
        window = gtk_window_new( GTK_WINDOW_TOPLEVEL );
        gtk_container_add( GTK_CONTAINER( window ), button );

        gtk_widget_show_all( window );

        gtk_main();

        return( 0 );
}
-- 

The window starts very small ... every time I click the button, it gets
bigger.
