However gevent depends upon greenlet and the .msi version I found fails to install and the egg for 2.6 refuses to install.
The msi version fails as follows.
C:\Windows\system32>easy_install greenlet
install_dir C:\Python27\Lib\site-packages\

greenlet.c : fatal error C1074: 'IDB' is illegal extension for PDB file:

I guess this means that I have a wrong version of VS.
Is there anything else I can use?
I want to get PyQt4 so the GUI won't lock up if the database can't be reached or takes ages to reply.

gevent is a coroutine -based Python networking library that uses greenlet to provide a high-level synchronous API on top of the libev or libuv event loop. Features include: Fast event loop based on libev or libuv. Lightweight execution units based on greenlets.
gevent is a coroutine-based cooperative multitasking python framework that relies on monkey patching to make all code cooperative. Gevent actually draws its lineage from Eve Online which was implemented using Stackless Python which eventually evolved into eventlet which inspired gevent.
greenlet 1.1. 3 The “greenlet” package is a spin-off of Stackless, a version of CPython that supports micro-threads called “tasklets”. Tasklets run pseudo-concurrently (typically in a single or a few OS-level threads) and are synchronized with data exchanges on “channels”.
By default, Gunicorn uses a synchronous worker class to serve requests, but it can be easily configured to use gevent by simply adding -k gevent to the run command.
This worked for me:
Grab the gevent installer from the Unofficial Windows Binaries for Python Extension Packages
Install greenlet from that same site
And if you're on a 64-bit Windows 7 machine and are having trouble installing, read this too.

You should ask the maintainer of greenlet to build .msi for Python 2.7.
I did it here: greenlet issue #17
Update: There are now builds for Python 2.7 on PyPI: http://pypi.python.org/pypi/greenlet
