Question

******You do not need to get everything working exactly as it says, I mostly just need an outline of how to create this GUI and add up the costs and print them all out. Any help at all will be greatly appreciated*******

Design and implement a Java program that creates a GUI that will allow a customer to order pizza and other items from a Pizza Paarlor.  The customer should be able to order a variety of items which are listed below. The GUI should allow the customer (via JavaFX UI Controls - text areas, buttons, checkbox, radio button, etc.) to input the following information:

• Customer Contact Info (Use text fields to input these from user)
  • First Name
  • Last Name
  • Phone Number
  • Address
• Type of food that can be ordered are: (Use dropdown menu to pick)
  • pizza
    • Small
    • Large
  • calzone
  • garlic knots
• Quantity of each food item being ordered (Use text field that only accepts numbers to type in a number between 1 and 50 )
• • Pizza toppings (Use dropdown to pick)
    • Plain
    • Extra cheese
    • Mushrooms
    • Pepperoni

  Pricing (assign these prices to each item)

  Base Price for items :

• Small Plain Pie –  $11.25
• Large Plain Pie –  $14.00
• Calzone - $7.75
• Garlic Knots -$3.50

• Additional fees for Toppings:

• Small Pie - $2.00 per topping
• Large Pie - $3.00 per topping

Conditions:

• The GUI will have two buttons. The first will be used to create a running total of the current order. This button should be clicked every time an item is added to the order to give a current total of the order.
• The second button will be used to print the following:
  • Customer Contact Info
  • All items and the quantity ordered
  • The grand total for the order
