How to use wish to connect to a separate executable that uses stdin/stdout?

[gtoal]

"Wish is a library that helps writing these kind of apps using Go." - I don't know anything about Go - I have existing programs that were not written in Go which I would like to make available over this style of anonymous ssh connection. These programs simply read and write via stdin and stdout, i.e. standard unix command-line programs. Is there a wish application that can be used to invoke a given program when you connect over ssh? I can handle fetching wish and building it but I don't want to have to rewrite applications in Go. I just want to use ssh pretty much the same way that we used to use telnet ports. Is this possible, and if it doesn't already exist, may I suggest it as a feature or add-on utility to be included? (One which can be built along with the wish suite and which doesn't require learning Go in order to use.)
PS The application should be able to work even if it sets cooked or raw mode, i.e. transparent pass-through, not just for line-buffered I/O.

Thanks!
