I am trying to make a GUI shipping calculator for the has you enter information and when you submit it it will give you the ground total. It also has to have the output write to a text file for each country that is used. I have the code down for the console and have written the GUI to how it should look, but am not sure how to convert the same program that works fine in the console through the GUI. Please re-write the following code to imlement input and display on the GUI:
