New GTK

[zippo <zippo752001 comcast net>]

I am new to writeing GTK, and i am trying to write a GTK icon clicky thing that when you click the button a 
program starts. I have writen some quick code but i don't know if it is writen correcly, also i don't want it 
to have the header, or the default top of the window. "The little part with the Tittle close, min and max 
buttons." But i dont' know how. here is my code:

#include <stdlib.h>
#include <gtk/gtk.h>

/* Create a new hbox with an image and a label packed into it
 * and return the box. */

static GtkWidget *xpm_label_box( gchar     *xpm_filename )
{
    GtkWidget *box;
    GtkWidget *image;

    /* Create box for image and label */
    box = gtk_hbox_new (FALSE, 0);
    gtk_container_set_border_width (GTK_CONTAINER (box), 0);

    /* Now on to the image stuff */
    image = gtk_image_new_from_file (xpm_filename);

    /* Pack the image and label into the box */
    gtk_box_pack_start (GTK_BOX (box), image, FALSE, FALSE, 3);

    gtk_widget_show (image);

    return box;
}

/* Our usual callback function */
static void callback( GtkWidget *widget,
                      gpointer   data )
{
    g_print ("Hello again - %s was pressed\n", (char *) data);
}

int main( int   argc,
          char *argv[] )
{
    /* GtkWidget is the storage type for widgets */
GtkWidget *window;
GtkWidget *button0;
GtkWidget *button1;
GtkWidget *mainbox;
GtkWidget *box0;
GtkWidget *box1;

gtk_init (&argc, &argv);

    /* Create a new window */
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

gtk_window_set_resizable (GTK_WINDOW (window), FALSE);


    /* It's a good idea to do this for all windows. */
g_signal_connect (G_OBJECT (window), "destroy", G_CALLBACK (gtk_main_quit), NULL);

g_signal_connect (G_OBJECT (window), "delete_event", G_CALLBACK (gtk_main_quit), NULL);

    /* Sets the border width of the window. */
    gtk_container_set_border_width (GTK_CONTAINER (window), 0);

    /* Create a new button */

button0 = gtk_button_new ();
button1 = gtk_button_new ();


    /* Connect the "clicked" signal of the button to our callback */
 g_signal_connect (G_OBJECT (button0), "clicked", G_CALLBACK
(callback), (gpointer) "Load XMMS");

g_signal_connect (G_OBJECT (button1), "clicked", G_CALLBACK
(callback), (gpointer) "Load GIMP");



    /* This calls our box creating function */
 box0 = xpm_label_box ("xmms_32x32.xpm");
box1 = xpm_label_box ("gimp_hi_32x32.xpm");
mainbox = gtk_vbox_new (FALSE, 0);

    /* Pack and show all our widgets */
gtk_widget_show (box0);
gtk_widget_show (box1);

gtk_container_add (GTK_CONTAINER (button0), box0);
gtk_container_add (GTK_CONTAINER (button1), box1);

gtk_widget_show (button0);
gtk_widget_show (button1);

gtk_container_add (GTK_CONTAINER (mainbox), button0);
gtk_container_add (GTK_CONTAINER (mainbox), button1);

gtk_widget_show (mainbox);

gtk_container_add (GTK_CONTAINER (window), mainbox);

gtk_widget_show (window);

 /* Rest in gtk_main and wait for the fun to begin! */
 gtk_main ();


any input on better ways to write it, and the header problem would be most greatful. Jason
