Overview: The program will create a Graphical Interface as a continuation of Project #1. A user of your program will be able to get suggestions from the Expert System or add additional information to the Expert System. This project encourages your creative exploration of various GUI components. Although there are no set design criteria, here is a list of possible components and requirements Picture / Graphics Label . Text field Radio buttorn Check box . Drop Down list Slider Scroll bars Buttons Attractive layout of components and ease of use At least 8 different components .
