Need Help Adding Functionality to GUI!

Hey Guys,

I'm trying to add functionality to a simple GUI as part of an assignment I'm doing, but unfortunately, I know very little about java - the most I've managed to do before now is create a simple calculator!

This is the GUI:

I need to capture the user input and write it to a text file, and then allow them to select their entry and edit it/remove it/add a new entry. Hopefully it's self explanatory from looking at the screenshot what I mean.

Ordinarily I'd be happy to teach myself through Youtube and searching forum posts, but I'm really pressed for time on this assignment! Any help would be greatly appreciated!

Thanks!

PS> I'm using Netbeans 7
