Create a simple windows order program in Java.

Make a windows program in Java that works as a cash register for a Pizza Parlor. This pizza parlor serves small, medium, and large Pizzas for 8, 10, and 12 dollars.

You can use 3 buttons (to place an order for the size), one button and 3 radio buttons (to place the order and choose the size respectively), or a button and a listbox (to place the order and choose the size respectively.) This part handling the size is up to you.

You must have a list box or combo box to hold the choice of toppings. (You can do this by making a multiple selection one, or having a couple of the side by side for Topping 1, Topping 2, etc. This design choice is up to you. You just have to demonstrate a list box or combo box in this program.)

(You can create a Java application and add a JFrame to the project and use the toolbox to drag the controls over. You do not have to create them manually in code.)
