backButton.setSize(20,20);
backButton.addActionListener(new ActionListener() {

What is the error you are getting when you compile?
The first thing I notice is that try to instantiate an ActionListener ("new ActionListener()") but ActionListener is an interface, not a class, and thus cannot be instantiated.
You could let your main class implement ActionListener (and add an actionPerformed method to that class). Or, even better, you could do something like this:
JButton backButton = new JButton(new HideDateMenuFrameAction());
private class HideDateMenuFrameAction extends AbstractAction {
public HideDateMenuFrameAction() {  
super("Back to main menu");
public void actionPerformed(ActionEvent e) {
dateMenuFrame.setVisible(false);
