I've searched half the internet and I can't find anybody who has had this same problem.
I've tried several different ways to add a vertical scroll bar, but in vain. Every other post I've seen describing this problem did the following:
JTextArea ta = new JTextArea();
JScrollPane sc = new JScrollPane(ta);
and that seemed to work for them. But I'm out of luck and have tried at least thirty different ways that I've found. I'm new to java and the class I'm in is killing me. Thanks for your time.

The problem you're facing (the JTextArea expanding) is caused by the fact that you added the JTextArea to the container instead of the JScrollPane.
Here is the logic behind what you should do :
JTextArea is contained by JScrollPane and JScrollPane is contained by the JFrame.
Change this line
add(outputArea, gbc);
to this
add(scroll, gbc);
