You can get the GdkWindow from the gtkWidget structure (widget->window),
but I am not sure this is the right interface for it.  Anyway, I've
attached a program that uses this to give you the position of a window.

#include <gtk/gtk.h>

static void
button_clicked (GtkWidget *button, GtkWidget *win)
{
  int x, y;
  GdkWindow *gdk_win = win->window;
  gdk_window_get_root_origin (gdk_win, &x, &y);
  g_print ("window is at (%d,%d)\n", x, y);
}

int
main (int argc, char *argv[])
{
  GtkWidget *win;
  GtkWidget *button;

  gtk_init (&argc, &argv);

  win = gtk_window_new (GTK_WINDOW_TOPLEVEL);

  button = gtk_button_new_with_label ("Send");
  gtk_container_add (GTK_CONTAINER (win), button);

  gtk_signal_connect (GTK_OBJECT (button), "clicked",
		      GTK_SIGNAL_FUNC (button_clicked),
		      win);

  gtk_widget_show_all (win);

  gtk_main ();

  return 0;
}
