This is how I compile test.c
gcc -Wall `pkg-config --cflags gtk+-2.0` -o test test.c `pkg-config --libs
gtk+-2.0`

Ok, sorry about that.

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

void

   static GtkWidget *cbwindow = NULL;

   if (!cbwindow)

       GtkWidget *text_view;

       text_view = gtk_text_view_new ();
       gtk_widget_set_size_request (text_view, 200, 150);

       cbwindow = gtk_window_new (GTK_WINDOW_TOPLEVEL);
       gtk_window_set_title (GTK_WINDOW (cbwindow), "Callback window");
       gtk_window_set_transient_for (GTK_WINDOW (cbwindow), parent);
       gtk_container_add (GTK_CONTAINER (cbwindow), text_view);
       gtk_container_set_border_width (GTK_CONTAINER (cbwindow), 12);

   }
   gtk_widget_show_all (cbwindow);
}
