I made the GUI. Tell me what your issue is with JFormDesigner. It is a great tool that makes your life a helluva lot easier. People like you annoy me, getting uppity because someone used a tool to make something rather than writing it completely from scratch. :l
Ask Jason to show you the copy I gave him that I made in ~5 minutes of your GUI. People like you annoy me. If you're going to cry about constructive criticism then you shouldn't even be writing scripts. The version I gave Jason (which is basically identical to your GUI) was 52 lines I believe, whereas your JForm generated version...
Not sure how saying "Jason you've broke my heart. JFormDesigner... </3." Is considered to be "constructive criticism" lol.
Anyways, nice script..
