Ok, let's try to be more scientific.
The only mentions of Babylon I could find from a quick Google search
date back to the late 90's. Is Babylon available for download
somewhere? Is someone actively developing it? From your words, it
seems like you're already running it on another Lisp implementation.
Is that the case? If yes, which implementation?

ABCL fully implements ANSI Common Lisp, but Babylon might use
implementation-specific extensions, or techniques like tail recursion
that don't work well on ABCL (since you're mentioning stack overflows,
that might be a reason).

If everything else fails, you can always run Babylon where you're
running it now, develop a communication protocol to talk with it
remotely, and use a JVM client with ABCL speaking the same protocol to
do whatever GUI stuff you want. This is easier than it sounds in Lisp
because, security and efficiency concerns aside, you can just send
printed S-expressions back and forth.
