Very basic Restaurant Order Management System in Java

Need to build a very simple restaurant management system that acts as a digital menu for a company under the name "Foodies". Technology - Java, along with the GUI ( very minimal). It should use a backend Mysql database. Timeline - Less than 1 week App Features - The opening page when the program is started should be three separate options for login: Customer, Chef, and Admin. This should be just three simple large buttons that span the entire page. When the respective button is clicked the user is taken to the respective login page, so if the "Customer" button is clicked, the customer is taken to the "Customer" login page where they can input the username and password. This should display an error message if the password/username is incorrect or if the field is empty. Below is the requirements for each of the login pages: 1. Customer Login - The customer is directly taken to the Menu page which displays the items that are split into categories of Starters, Mains, Desserts, and Beverages. The customer should have the ability to switch between these sub-menus Each line of the item food should have the Item Name, Item Description, Price and +/- buttons to indicate how many the customer wants to order The top right should be a "Proceed" button where the customer can continue to check-out, but first they are taken to a "Receipt" page which displays their total order and the cost. One this page the customer can choose to "Go Back" or "Confirm Order" After they have confirmed the order they are taken to the thank you message and then the program goes back to the login screen 2. Chef Login The chef's login is initially directed to the "Uncompleted Orders" page which shows the Table number (As the customer logins are respective to each table at the restaurant), the items ordered, and the order date and time. The chef can have a button called "Order Finished" to click which displays a pop-up message stating "Order for Table X Completed" There should be a sub-menu to go to the completed order page which shows each order that had been previously taken Log-out button in the top-right to take them back to the initial page 3. Admin Login - Revenue statistics page which shows the revenue made for the past month. The revenue should be split initially by each sub-category of ''Starters", "Mains" etc. but then a total below. "View Graph Button" to generate a simple graph that showcases total revenue each month. It does not need to be a complex graph with variables that change. The graph is displayed as a bar chart that is a pop-up window. Order statistics page similar to the revenue page that shows how many of each item was ordered in total. View graph button to display a pop-up window of a bar chart that is the number of orders (y-axis) against the food item (x-axis) - A separate sub-menu to add new menu items, remove previous ones and edit certain features of the previous ones. They should be able to change the item name, description and price. T - An option to create or delete Customer and Chef login information, such as the ability to make a new account.
