I think I might know what you are looking for: I have been searching for something simmilar whan I used to work a lot on Unix and wanted a similar experience on my Windows machine: http://sourceforge.net/projects/console/.
Since then, however, microsoft came out with Power Shell 2.0 which comes with a very interesting enviroment: graphical Powershell. However, I haven't been playing with it since I don't do any scripting anymore and I don't even know if the thing can be used for anything outside of Power Shell.
Edit: I fogto there was also cmdplus.
Edit2: This seems very interesting, but I don't know how usable it is right now: http://poshconsole.codeplex.com/
