Do you have control over the design of that panel?
If so, a better design would be to move those
buttons out of that panel.  The panel should
concern itself just with presenting the data
germane to it, not controlling the environment
in which the panel is nested.  Instead, the
dialog should own those two buttons: they are
dialog, not list panel, controls.

If you have to have those buttons on that list panel,
add the ability to access them to the panel, and
then add ActionEvent listeners to them from the 
dialog:

  public class MyListPanel extends ... { 
    ...
    public JButton getOkButton() { return this.okButton; }
    public JButton getCancelButton() { return this.cancelButton; } 
    ...
  }

  public class MyDialog extends ... { 

    public MyDialog(...) { 
      try { 
        jbInit(); 
        this.listPanel.getOkButton().addActionListener(
          new ActionListener() { 
            public void actionPerformed(...) { 
              // handle OK action
            }
          }
        );
        // do the same with the cancel button.
      }
      catch (...) { ... }
    }
  }

Or, if you don't want to give direct access to the 
buttons, you could just add methods to the MyListPanel
class which allow you to add listeners to those buttons
directly:

  public class MyListPanel ... { 
    ...
    public void addActionListenerToOkButton(ActionListener l) { ... }
    public void addActionListenerToCancelButton(ActionListener l) { ... }
    ...
  }

But really, just move those buttons to where they
properly belong.  Do things correctly from the outset
and you (and we?) will have less work to do.
