Is there any beginners guides to making web interfaces?

Looking to try and either modify the default skin or create a totally new one from scratch.

Using Kodi 14 in the latest stable Openelec

Not that i know of. But you can study the code of existing ones. thats how i strated. The first crackpoint is to send something over json/rpc. anotherone is the whole packing for zip. there you can also take adavantage of other plugins.
a few things apply for all plugins. you can read them here: http://kodi.wiki/view/Add-on_structure

share with us what you are doing!

a smaller project is porthole, i guess it's a good start since the code is small.

also this site you will need a lot: http://kodi.wiki/view/JSON-RPC_API/v6

you can anytime ask questions here.

i also recommend web-dev plugins for the browser. like firebug for firefox for example.
