You can write daemons in basically any language out there.

Sure -- see http://code.activestate.com/recipes/66012/ for an example

Here is an example on how to run a Python script as a Unix daemon:

http://svn.plone.org/svn/collective/bda.daemon/trunk/bda/daemon/daemon.py

Basically it forks twice and redirects open file descriptors to /dev/
null.

On Windows, 'daemons' are called services. You can write Windows
services in Python using the Pywin32 extension. See Mark Hammond's
book for an explanation.

Basically it forks twice ...

What's the advantage of forking twice over forking once and calling setsid?

Also, on Windows, you can get good results using srvany

I've set this up to run Pyhton for a couple of scripts.
