Request: Custom UI

[Rustycage]

I was wondering if someone could school me on how to make a custom UI for what the API currently supports, and work with me on a project of making a great set of UI skins available for users to use, and maybe some addon's to go with it in case users want to use them.

I was thinking of something like this:

Or these:

Thanks for your time.
