Here is a script/tool I wrote a while back (when I wanted to see what Lisp was all about), where I created a REPL Gui based on the amazing Clojure-clr project (which is CLR port of Clojure)
You can download this O2 Platform tool from: Util - Clojure-clr REPL (Lisp) v.2.0.exe
This is a 9Mb standalone exe (only requirement is the .NET Framework 4.0 running on a Windows box):
which looks like this when executed:
As with all the other O2 Platform based REPLs, this is a real time execution and compilation environment:
Since you (like me) are most likely new to LISP, I included in this tool a Samples drop-down menu containing a number of LISP code snippets:
Note: these code examples were based on the great http://tryclj.com/ online tutorial:
For reference, here are the LISP Code Snippets in action:

Arithmetic
Division
Multiple sums
