Pizza Order Graphical User Interface

In this week's practice program we are going to build a "Pizza Order" graphical user interface that collects the order information for ordering a Pizza (we can then use the BMI program to see how bad pizza is for you!).

Each pizza order will contain

Customer first and last name

Pizza size (only one can be selected)

Small: $6.99

Medium: $9.99

Large: $12.99the default

Toppings (multiple selections)

extra cheese: $1.50

sausage: $2.25

ham: $2.25

After each item is selected the total cost should be updated and displayed.

There shall be command buttons and menu options for the following operations:

Total Orderdisplays the total price of the order

Clear Itemsclears all the input fields, except for the customer name

New Orderclears all the input fields, and creates a new order

Exit the application
