Please define what "not working" and "working" mean.

I see that pressing the back button seems to create a new "Menu" object. What is this Menu object, and how will creating a new one do anything for your GUI?

And your tittle misleading too. Anyway, specifically ask your question please rather posting a long code.

[hardwired]

    // Instantiate the Back button
    Back = new JButton("Back");
    // and add the ActionListener to the Search button.
    // But wait, you already added the listener to the
    // Search button above - just after you instantiated
    // it. So this next line is not needed.
    Search.addActionListener(this);
    // Instead, this would be a good place to add the
    // listener to the Back button:
    // Back.addActionListener(this);
    c.add(Back);
    ...
public void Back_actionPerformed(ActionEvent e)
{     
    Menu Menu = new Menu();
    // This method is never called because the ActionListener
    // which calls this method was not added to the Back button.
    // If you add the listener and this method does get called
    // it doesn't do anything anyway. You could put a println
    // statement in here to see if the button-listener-method
    // sequence fires, eg,
    System.out.println("Back_actionPerformed");
