Custom GUI

Hey there. I was just reading this old topic I found somewhere in the forum.

http://forum.baldursgate.com/discussion/4431/a-new-screenshot-approaches

I couldn't reply (dunno why, maybe the topic is closed), but I would like to know if there's a mod that can customize the GUI. Giving a fresh look to the game like this (http://nsa30.casimages.com/img/2012/09/11/120911074534708582.jpg) would be very nice.
Thanks.
