Looks like the "Go support" is just running a precompiled binary that starts a TCP listener (https://github.com/aws/aws-lambda-go/blob/master/lambda/entr...), so might not be that hard to port...
if it's a "json" like data that is sent to you (i.e a structure made out of only primitive types and list/dict) it may be not that hard, but I think it will be a work with very few value outside of this very specific use case.
