Dale,

The dcuair decoder actions provided in 
$NAWIPS/ldm/etc/templates/pqact.gempak_decoders.in
have a pattern for operational dropsonde data in the real-time IDD data stream.
Once decoded into GEMPAK upper air files, NSHARP can be used to display
the dropsondes by clicking on the "DROP" file type under the Observed Soundings.

If you have other data not in the broadcast format that you want to get into 
GEMPAK format,
the easiest way to to create an ASCII input file in the format that SFLIST 
outputs such
as:
http://www.unidata.ucar.edu/software/gempak/tutorial/answers/snlist_answer1.html

Once data is in this type of format, use the SNEDIT program to read the data in 
to 
a GEMPAK file.

If you can describe your data, or expected format, I can help in
how to format your data for use with GEMPAK.
