Maybe 'slim'?

Many of those packages are probably pulled in by some "gnome-desktop"
meta-package.  If you want a minimalist configuration you should be able
to dump the meta-package.

lubuntu is based on LXDE <http://wiki.lxde.org/>.  LXDE uses
GTK2.   It has been trouble-free in practice, and is an optional
install in many linux distros.  I generally keep an lubuntu VM
around and put a small lubuntu partition on any Windows
machine that needs something useful to do with those long
winter nights.

Knoppix has a version (microKnoppix CD) that uses LXDE.

You can try out LXDE with lubuntu or microknoppix to see if
it is suitable for you.
