Adding a new reputation

[nkttennessee]

I am extremely new to wow modding but I am trying to add a new reputation that will show up in a characters reputation tab. I believe I am successfully keeping track of the reputation amounts and updating them accordingly. However, I am very lost on gui elements and how to render my added reputations in the reputation tab of the character frame. Any examples, tutorials, or information would be greatly appreciated.

Left is current reputations, right is what I'm trying to add.
