I was wondering if anyone has developed the ability to plot a wind rose using the IDV?

Not that I know of.

The ideal widget would allow me to load a gridded data set and choose a location from the plan view to calculate a wind rose for that location.

Do you want a wind rose over the time steps?

A suitable type of plot can be found at the NCL web site:
http://www.ncl.ucar.edu/Applications/rose.shtml

Does anyone out there know both the NCL and Jython languages who might be able to help convert this code?

One could get the u,v values using GridUtil.sampleAtPoint on the flowvector field. Then it's just some math and plotting. ;-) I'm not sure converting from NCL will get you the plotting, though.
