Above should be:
  GdkPixmap *pixmapdata;

Above should be :
  gtk_window_set_title(GTK_WINDOW(window1), "window1");

Here you need either gtk_widget_show (which also does realization of a 
widget) or gtk_widget_realize (and then use gtk_widget_show() later), not 
both. On a side note, if you create pixmap first and realize window later, 
code will still compile, but it will give you a warning:

Gdk-WARNING **: Creating pixmap from xpm with NULL window and colormap

Here you need to add your pixmap to the window:

gtk_container_add(GTK_CONTAINER (window1), pixmap1);

>   gtk_widget_show (pixmap1);
>   gtk_main ();
>   return 0;

This should work fine, although I have no idea if your gnome initialization 
is correct...for the reference here's source code for pure gtk (no gnome 
support) that runs correctly:

#ifdef HAVE_CONFIG_H
#  include <config.h>
#endif

#include <gtk/gtk.h>

int main (int argc, char *argv[]) {
  GtkWidget *window1;
  GtkWidget *pixmap1;
  GdkPixmap *pixmapdata;

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

  window1 = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_object_set_data (GTK_OBJECT (window1), "window1", window1);
  gtk_window_set_title (GTK_WINDOW (window1), "window1");
  gtk_widget_realize(window1);       
                             
  /* Ant.xpm is the name of the file with the pixmap, which sits in the same
   * directory as main.c
   */
  pixmapdata = gdk_pixmap_create_from_xpm (window1->window, NULL, NULL, 
"Ant.xpm");
  pixmap1 = gtk_pixmap_new (pixmapdata, NULL);
  gtk_container_add(GTK_CONTAINER(window1), pixmap1);
  gtk_widget_show_all(window1);

  gtk_main ();
  return 0;   
  }
