How can I display LISTS from this code?

I have this working code attached in Code Snippet, now I need to show it in LIST with SCROLLS instead of ShowMessageDialog.
I got this sample code from a book but I don't know how to implement it to my old existing code. Anyone?

//  SimpleList.java
//
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class SimpleList extends JPanel {
    String label[] = { "Zero","One","Two","Three","Four","Five","Six",
                       "Seven","Eight","Nine","Ten","Eleven" };
    JList list;

    public SimpleList( ) {
        this.setLayout(new BorderLayout( ));
        list = new JList(label);
        JScrollPane pane = new JScrollPane(list);
        JButton button = new JButton("Print");
        button.addActionListener(new PrintListener( ));

        add(pane, BorderLayout.CENTER);
        add(button, BorderLayout.SOUTH);
    }

    public static void main(String s[]) {
         JFrame frame = new JFrame("Simple List Example");
         frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         frame.setContentPane(new SimpleList( ));
         frame.setSize(250, 200);
         frame.setVisible(true);
    }

    // An inner class to respond to clicks of the Print button
    class PrintListener implements ActionListener {
        public void actionPerformed(ActionEvent e) {
            int selected[] = list.getSelectedIndices( );
            System.out.println("Selected Elements:  ");

            for (int i=0; i < selected.length; i++) {
                String element =
                      (String)list.getModel( ).getElementAt(selected[i]);
                System.out.println("  " + element);
            }
        }
    }
}
