It is off-topic because there is nothing Cygwin-specific about the process to
getting this working.  So unless you can point to how this works on some
other platform and not on Cygwin, you need to find a good book, site, or
forum for ssh tunneling information.  Consulting the man page is a good start
if you haven't already.

I don't know what lines you typed to get the above error but I'm guessing from
the error you typed:

ssh -f -L 5901:localhost:5900 -N -C -o Compression=yes -o CompressionLevel=9 
zlib@openssh.com

I can't reproduce your issue.  When I try it, it tells me:

ssh: connect to host openssh.com port 22: Connection timed out
