Thanks Karl for your prompt reply. 

I am sending you the whole source code. Hope this will give you a hint. I 
will buy you a drink if my program runs:-) You see I have spent almost 2 days with his troublesome program.



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

class Launcher:public Gtk_Window
{
public:
  Launcher();
  gint delete_event_impl(GdkEventAny*){
    Gtk_Main::instance()->quit();
    return 0;
  }
private:
  Gtk_VBox* vbox;
};

Launcher::Launcher()
{
  
  vbox = new Gtk_VBox();
  add(vbox);
  vbox->show();

  Gtk_Button* button;
  button = new Gtk_Button("Kterm");
  vbox->pack_start(button);
  connect_to_function(button->clicked,&system,"kterm &");
  button->show(); 

  button = new Gtk_Button("Netscape");
  vbox->pack_start(button);
  connect_to_method(button->clicked, Gtk_Main::instance(), &Gtk_Main::quit);
  button->show(); 

}

int main(int argc, char **argv)
{
  Gtk_Main m(&argc, &argv);
  Launcher l;
  l.set_title("My Launcher");
  l.show();
  m.run();
  return 0;
}
