Car Parts Inventory Program

This project is for my Automotive Repair business. We keep several types of parts in stock that are used daily, and we need to start keeping track of them so we can know what to order. I have another program made in Java that I want to tack on (I have the knowhow). Here is what I want: -Java Language -GUI Program The program must store part Name, Quantity, and Part number. Must be able to be sorted by all 3 types. I want to be able to save the data to a file, and open it up so I can use it on more than one computer. I must be able to add, modify, and delete parts on demand. Keeping the GUI clean and easy to use would be nice, as it will cut down on confusion with my employees. Please comment the code if you can, as I would like to use this code to further my java knowledge. (I am self-teaching) Thanks.
