Active Windows Dock? Does this exist/is possible?

Just wondering, i havent been able to find a setting where I can add "list active windows" so somewhere on my screen it shows all the applications I have running.  This is just like windows does on its regular taskbar (not the start button, quick links, or time/process display on the far right).  For now I can just alt tab like crazy, but it would be neat if I could get an active windows dock and not have to grab windows blinds just for that.

Thanks in adanced and thanks coming later...
