It isn't really. I have built OpenSSL using MSVC, BC and mingw.
I have a file here called openssl-0_9_7_Patch_VisualStudio6.zip culled from
the OpenSSL mailing list. I haven't tried it; if you want, I can send it to
you off-list.

I always suggest learning by doing. The OpenSSL C API is quite big, but
there exists wrappers in Perl, Python, Tcl, Ruby, Lisp and possibly
whatever high-level language you can think of. (I have one; see .sig.)
These makes programming OpenSSL more accessible.
While your test programs are running, use ekr's excellent ssldump to see
the stuff happening on the wire.
There is also a book called SSL and TLS Essentials by Stephen Thomas that
just describes the protocol. Refer to the book while you're running your
programs and marveling at ssldump's output.
Have fun.
