In addition to what was said, ZeroMQ can be used from lots of language through bindings. I haven't seen yet way to use Go written code as library (shared or static) to another language/runtime. "C" gets you there, if you keep clean "C" interface, and don't let exceptions escape if you have been somehow using C++ internally. I've had no problem using zeromq directly through the luajit ffi bindings for example.
