You are required to create a class in Python which can hold the following information: - Pizza Type e.g., Pepperoni, Margarita etc. - Pizza Size e.g., (Small Pizza - \$5, Medium Pizza - \$7, Large Pizza - \$9) - Toppings e.g., 3.0 (Olives - \$3, Mushrooms - \$2, Onion - \$1) - Pizza Price e.g., 18.0 - Quantity e.g., 2 - Customer Name e.g., Mohammad Salim The class should have default constructor, setters, and getters methods for the above class. Add the 5% VAT value to the actual bill and return the final amount. You may make multiple functions to calculate the final bill. Develop the Graphical User Interface (GUI) of the above scenario - Calculate Bill (Button) - This button will calculate the bill based on user selection and display the bill along with customer name. - Reset (Button) - Clicking on resetting button will reset the form back to default. - Validate the program and make sure that the program provides useful information when a wrong selection is made such as entering numbers instead of text in the customer's name text field
