[JAVA]: Posizionamento JLabel in un frame

[gax80]

purtroppo sto alle prime armi, e il concetto di layout nn mi è chiaro, questo è il mio codice:

class Main_Panel extends JFrame implements ActionListener {
//private JPanel p = new JPanel(new GridLayout(1,1));         
private JButton b = new JButton("inserimento script");
private JLabel l = new JLabel(); 
private Color c = new Color.BLACK;
//Icon icon = new ImageIcon("C:/Documents and Settings/G.Costanz0/Desktop/Logo.gif");

Main_Panel(){
    
        JPanel p1 = new JPanel();
        JPanel p2 = new JPanel();
        JPanel p3 = new JPanel();
       
        setTitle("ScriptManager");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Dimension d = getToolkit().getScreenSize();
        setSize(d);
        //getContentPane().add(p);
        getContentPane().add(l);
        Image img = getToolkit().createImage("C:/Documents and Settings/G.Costanz0/Desktop/Logo.gif");
        ImageIcon icon = new ImageIcon( img.getScaledInstance(750, 250, Image.SCALE_DEFAULT));
        l.setIcon(icon);
        l.add(b);
        l.add(p1);
        b.setSize(145,50);
        b.setLocation(10,200);
        //p.add(p1);
        b.addActionListener(new ActionListener() {
