Text field saving

Post up what code you have and someone will explain. Have you attached a listener to button to listen for mouseclicks? if so do you know how to get the text from a texfield? it has a method for this in the api. If all that is complete then take a look at this snippet.

If you are still not sure then post what code you have.

That should work fine. A few things though, there is a lot more to learn in Java than simple form building in Netbeans. Also it is bad to have mix logic in with the GUI code, usually this would be separated in another class.

You should always start class name off with an Uppercase letter.
