This is my GUI now.

So my problems here are that:
1. I need to display my variable stock next to where I say Stock is
2. I need to display my variable money next to where I say Your Money is $
3. I need that text field input to be variable hE
4. I need that button to link to another jPanel that displays a bunch more variables
So basically this boils down to: How to link a text field to a variable, how to display a variable, how to create more than one panel (do i need to make another class?) and how do I make the button click display that next panel (action Listener here?). I can link the code for both the program and the GUI if needed, but im making it in Netbeans Design view, not hard-coding it.
Sorry for the hefty request, by the way

I'm also okay if you link a good tutorial...I tried the one on the Oracle site with Netbeans, but didn't really get it from there.
