        add(btn1);
        btn1.addActionListener(new lytter());
        
    }
    }
    
    class center extends JPanel {
    public center() {
        
        area = new JTextArea(8,1);
        JScrollPane scroll = new JScrollPane(area);
        add(scroll);
    }
    }
    
    class south extends JPanel {
    public south() {
        lbl = new JLabel("antall: " + myList.finnAntall() );
        add(lbl);
    }
    }
    
    class lytter implements ActionListener {
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == btn1) {
        int nu = Integer.parseInt(JOptionPane.showInputDialog("nummer: "));
        String na = JOptionPane.showInputDialog("varenavn: ");
        double pr = Double.parseDouble(JOptionPane.showInputDialog("pris: "));
        
        boolean sett = myList.ny(nu, na, pr);
        
        if (sett)
            JOptionPane.showMessageDialog(null, "varen ble registrert");
        else 
            JOptionPane.showMessageDialog(null, "varen ble ikke registrert");
        }
            
    }
    }
    
    public static void main(String[] arguments) {
    GUI application = new GUI();
    }
}

never mind.
i have found out.

i had to put the "show()" at last.

    
setSize(400, 400);    
setTitle("test"); 
show(); 

thats kind of sick..
