The problem is , that first parameter of callback function is that 
widget which calls the callback and second parameter is that
registered by gtk_signal_connect as data. So when you put
gtk_widget_destroy functuion as a callback function, it allways destroy
widget which calls the callback (the cancel button). You have to write own
callback function for destroing widget given as callback data.

for example :

void KillWidget(object , data)
GtkObject *object;
gpointer data;
{
	gtk_destroy_widget(GTK_WIDGET(data));
}
