Reverse tunelling from office machine running Windows 7 for VNC, SOCKS and SSH

Reverse tunelling from office machine running Windows 7 for VNC, SOCKS and
SSH

My work machine runs Windows 7 and the workplace proxy does not route to
my home machine. I would like to access VNC(already setup using tightVNC),
SSH(already setup using openssh on Cygwin) and SOCKS proxy(not setup yet)
on my home machine (also running Windows 7).
Since I am unable to route directly to my home machine's public ip, I
cannot initiate a tunnel from my home machine and therefore, I need to do
a reverse tunnel from my Windows 7 work machine. However, all the
tutorials I have come across on the web is about Linux and none are about
Windows.
So, please tell me how do I initiate a tunnel from my work machine to the
SSH server on my home machine to access said services.
