Well, there are some ones. There is the PAQ family that are the best 
now. Of course they are research compressors mostly written in C++ 
but they exist. There is a freepascal/lazarus app that implements a 
GUI for this and other algorithms, at 
http://peazip.sourceforge.net/  (i'm not the developer).
