I posted a new version of this library. It contains a direct port of most of the WPILIB Java/C++ functionality, except for the I/O portion which LabVIEW already had.
Except for bug fixes, and probably some more samples, the library is complete.
You can find more information and get the download link here.

Happy roboting.
