You can use both modules through the SEXTANTE/GRASS interface
in gvSIG OADE 2010:

http://www.oadigital.net/software/gvsigoade

For instructions, see the PDF manual that will be copied
to your computer as part of the installation process.

Note that gvSIG OADE 2010 is now unmaintained. There is
a successor called gvSIG CE (www.gvsigce.org), which
will release a stable version in a few weeks (inshallah).
It will also include r.cva and r.prominence. But if you
need them right now, use OADE 2010. It works fine.

Both modules have not seen updates for a while, so I am not sure
that they will compile on GRASS 6.4.3 at all at this moment.

Unfortunately, OSgeo4w64 includes some MS Visual C/C++ projects
and some MSVC runtimes/DLLs, whereas the GRASS binaries that ship
with gvSIG use only open source MinGW DLLs, so I don't think you
can just copy the GRASS modules over (but it's worth a try).

I would say the same: Try if r.viewshed suits your needs first.
It's much more efficient than r.cva (though not as flexible and
convenient for cumulative analyses).

Alternatively, if you opt for gvSIG: Look in the SEXTANTE group
"Visibility & Lighting". There are many other options in there.

Best,
