Help with KG Panels

[Myridin]

Hello, after trying many, many different UI's and a lot of cussing at the computer, I've been trying to build my own UI (which I might then post here),
I've encountered one tiny problem. I have no idea how KG panels works. I have read through a few guides and it's still all Chinese to me.

So my question is, could anyone hear explain it to me in lament's English or maybe create something for me to use in my UI?
