How do I change the WoW GUI? : World of Warcraft General Discussions

Hey, I was looking at some sites/screenshots and found that people have their
GUI setup different. Ive tried a couple of things but I cannot figure
out how to get it as displayed in the image ive posted.
Cause i want to play the game with the setup this guy has for his WoW Client.
Chatlog Left, Chatlog Right, Macro Pannel Middle.

Could someone please assist me on this? Thanks

i dont know how to set it up exactly like that but custom gui's have been around for a while. here is a download site where you can look around at whats in it, download the one you want and follow the instructions

The button setup is created through Flexbar, a plugin available at most mod websites. Just run a Google Search for "World of Warcraft Flexbar" without the quotes. The chatbox can easily be seperated and moved by dragging one of the windows in the frame to a new location, creating two seperate chat boxes, such as one for chat and one for combat.
