Having Issue with inventory program

I have been trying to get this inventory program GUI to properly work. Several issues I am running into are:


Inability to pull my supplies into the GUI and be displayed from my main program.
Unable to get the buttons to work properly. (the quit button works)
My inventory should pop up when the program runs and the buttons should cycle correctly.
If I run my main program by itself, I get only a Gui box, nothing filled in it so something isnt being passed and I dont understand why.
I believe when I run my main program, The gui should run as well but im not sure how to get it to do that.

I honestly dont know how to compile my program ( im very noob with java and in dire need of a walkthrough)

I will post my code, but if there is someone who can offer me assistance and walk through this with me either on the phone, skype or something, it would be of great help. Feel free to tear into it and let me know in detail if you can what i need to change. Any help is appreciated.
