I haven't done it, but from looking at the OpenPlotter GPIO app, it looks like you can do what you want entirely in that app. Just get the pulses/second from that GPIO pin mapped properly to meters/second, then assign a relevant SignalK key to it. If you need to know what SignalK key you'll need to use, the SignalK web site has a reference document that should give you what you need. It will be something like environment.wind.speedApparent and/or environment.wind.angleApparent.
Once it's in SignalK, you can use it directly in OpenCPN and other OpenPlotter apps, or convert it to NMEA0183 or NMEA2000 as you need it.
