How to design an Inventory Program GUI

cblank

I need some help if someone could help me. I know everyone is asking for help in java. But for some reason I'm the same as everyone else when it comes to programming in java. I have an inventory program that I have built so far with no problem. But I cannot figure out how to turn it into a GUI application.
This is what I'm trying to get it to do.

Modify the Inventory Program to use a GUI. The GUI should display the information one product at a time, including the item number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory of that product. In addition, the GUI should display the value of the entire inventory, the additional attribute, and the restocking fee.

You need to answer the following questions:
1) What type of GUI am I going to design? Swing, Applet, JFrame, or ?
2) What controls do I need to add?

The gui program will be built using Swing. I have tried to program using the JAVA gui before, but I am not having any luck. I really dont know were to start. I have done ok up until now. Right now I just need The application to use a GUI to display the product information of one product, including the item number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory of that product.The GUI displays the additional attribute from the subclass, the restocking fee, and the value of the entire inventory.

Thanks,
