Use these classes:

JMenu
JMenuBar
JMenuItem

check the api for them.

The ideas is:
You create one JMenuBar.
You create some JMenus and you add them to the one JMenuBar.
You create some JMenuItems and you add them to your JMenus

Also there is this:

Thanks, that I've got. But problem is, how to change space under menu.. I can make some JPanel form, but how to write to action(jMenu1ActionPerformed) to display some JPanel, and to klick to another menu button to display another one.. I can't do it...

I assume that you can add an actionlistener to the menuItem using the addActionListener method. Look the API. When the menu is selected the actionPerformed method of the ActionListener is automatically called.

I believe that there is a remove method that removes components from the JFrame. I have never used it before, but I believe that if you add a JPanel to the JFrame and then you call the remove method with argument the same JPanel, it will be removed.
