Hello, I need help with my Python Project. I am trying to make a sandwich ordering GUI tkinter application. Like doordash but for one sandwich shop. My project requires a working GUI tkinter application with at least two windows. I need to take a modular approach in my application. I need consistent and clear naviagtion throughout the GUI application. There has to be two images with alternative text. I need at least three labels, three buttons, and three call$-$back functions with each button, including an exit button. I have to have Validation testing. I also need a user manual for the application.
