Yes it is possible and I'm tempted to add, obviously.
Examples do far better than attempting to provide a tutorial.
Look at the code in the edssl or stunnel or sproxy packages
for how they handle ssl in building tunnels for arbitrary protocols.
Alternatively, you could look at the Fetchmail sources
<http://www.tuxedo.org/~esr/fetchmail>. I wrote the SSL patches
for fetchmail to support pop3s and imaps. Those are largely confined
to the socket.c source file (other files had changes to support port
numbers and configuration options). You can see how all that's done
from those sources.
Mutt also has SSL support for imaps and would be another
example of how to impliment SSL tunneling on a protocol.
If you have some weird layer-violating or reverse connection
protocol (like ftp amongst others) you may have some challenges, but if
it's a straight forward, single connection, tcp protocol, you should
have no problem.

I don't do Windows. You're on your own there. :-)

Someone who works on Windows will have to help you there.
