I scrolled to the bottom of the link you gave and found
Powered by modified XBTT backend and TBZ frontend v0.97 0.97
and if you follow the clickable links....
http://xbtt.sourceforge.net/
However it does look like someone put a lot of design artwork into this. So best suggestion....give it a try on localhost and get it to where you want it and then go 4 it!!
