This requires either Squid-3, or Squid-2.5 + SSL update patch and some
tweaking.
With Squid-3 it is a fairly straight forward setup
https_port to make Squid listen for client requests
cache_peer to make Squid forward to the web server
What won't be possible with a setup like this is the use of client side
certificates for authentication to the application server, but pretty much
anything else imagineable is possible.

Good plan.

Squid-2.5 is not intended to be used like this. The standard release lacks
the capability of initiating ssl connections, and even with the SSL patch
it lacks a bit of flexibility in how to configure reverse proxies to make
the setup reasonable.
In Squid-3 there is not much to say about it as it is just a standard
reverse proxy configuration with https on both sides and there should not
be any major problems figuring out the required configuration from the
squid.conf documentation and release notes.
As you already figured out you need a good server certificate (+ key) to
give to Squid to accept the https requests.
