[Wrf-users] Question about GFS data retrieval

I don't know if this is the correct place to ask this but here it goes.
I'm trying to use GFS to get upper air winds at a specific altitude. I
found out about the partial http transfer using curkl and then wgrib to
get the data.
Now my question is:
I need to supply as variables the latitude, longitude, altitude and that
I want wind direction and speed. As an example, I would need the winds
at 38N020W at 33000ft (11000m or a specific pressure level) which would
then give me, for instance, 274/38 (274 degrees wind direction and 38
knots [or whatever metric used]).
I know that GFS has all this information, it's how to ask for it and how
to properly decode it that I'm in doubt.
Finally, the information I want must be treated in raw. Don't want any
images/graphs or the like.
What I'm using:
However the above doesn't let me specify latitude, longitude or altitude.
Thanks for any help,
