The document describes a fast food order program that is currently functioning well but needs a graphical user interface (GUI) for improved usability. The program includes features such as a menu display, item selection through user input, and receipt generation with tax calculations. The author seeks help from the community to implement the GUI component for the program.

1. Hello everyone,
I'm working on my fast food order project program. So far my program works perfectly. Now,
my instructor is requiring me to use GUI interface on my program. I have tryed but it has been
impossible. Can you please guys give a hand with this. Here is my program code:
