I believe you want to use the "geod" program distributed with PROJ.4.  The
man page, possibly a bit out of date is at:


Example use:
$ geod +ellps=WGS84

33 -117 15 10000

33d5'13.53"N 116d58'20.2"W -164d59'5.581"

So if you gave it an initial location of 33N 117W, an azimuth(bearing) of
15 degrees and a distance 10000m you would arrive at the output location
given with the third value being the azimuth back to the original point.

You should be able to construct what you want from this.

There is also a corresponding C API.

Best regards,
