The closest thing at the moment would probably be Lispbox (http://gigamonkeys.com/book/lispbox/) altough it's a bit outdated, so you'd be better with directly downloading SBCL (http://www.sbcl.org/platform-table.html). Use cl-build (http://common-lisp.net/project/clbuild/) for to ease library download. and install. I guess it's too complicated for a newcomer, but there's no easier way atm, sorry.
