GTK + PRGMMING - BUTTON SIZE UNCONTROLLABLE!!

[PRAKASH GOWRI <prakash_gs@xxxxxxxxx>]

HI,

	I am a beginer in gtk+ and I have created a window
with
three push buttons in it(The program is given below ).
But if I increase the size of the main window,
the sizes of the buttons will also increase
correspondingly.Is there 
any way to control size of the button and increase
only the size of 
the main window (Top Level window).Please let me know,
 



Regards 

Prakash G S



here is the code:

#include<gtk/gtk.h>

gint closeapp(GtkWidget *widget,gpointer data)
{
	gtk_main_quit();
	return(FALSE);
}

GtkWidget *pack(GtkWidget *box,char *label)
{
	GtkWidget *button;
	button=gtk_button_new_with_label(label);

gtk_box_pack_start(GTK_BOX(box),button,FALSE,FALSE,0);
	
	gtk_widget_show(button);
	
	return (button);
	
}


int main(int argc,char *argv[])
{
	GtkWidget *window,*button,*box;
	
	gtk_init(&argc,&argv);
	window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
	

gtk_signal_connect(GTK_OBJECT(window),"delete_event",GTK_SIGNAL_FUNC(closeapp),NULL);


gtk_container_set_border_width(GTK_CONTAINER(window),10);

	gtk_widget_set_usize(window,440,280);
			
	box=gtk_hbox_new(FALSE,0);
		
	button=pack(box,"aishu");
	button=pack(box,"sonali");
	button=pack(box,"kajol");
	
	
	gtk_container_add(GTK_CONTAINER(window),box);

	gtk_widget_show(box);

	gtk_widget_show(window);

	gtk_main();

	exit(0);

}
