I want someone to create GUI using tkinter on my code - python

The project about POS - Point of Sale, I built the code but I've never used Tkinter and the time is short to learn.. so the project will first ask the user if he/she is a customer or manager, (I haven't created manger code yet)if the customer then, the program will display 4 options (1.Main dishes, 2.Appetizer, 3.Desserts,4.Drinks) and each option has its own sub-menu along with the prices and quantities. The users will chose what they want to eat, then the item will be added into the cart along with the quantity and price; then the user will choose if he/she wants to remove an item, add more items, exit, back to the menu, or proceed to check out. if the user chose to proceed to check out the user will have the option to choose what payment method could be (cash or Paypal) .. then the paid amount of money will be displayed along with the change; then if the user paid the receipt will be displayed or as a pdf. I really don't mind if you made adjustments to my code, and am open to everything. further details will be provided once I chose.
