I run windowmaker as my primary window manager. The distro I run is SuSE 10.0. Gnome Apps have very ugly/large fonts, when windowmaker starts up. This can be solved by running '/opt/gnome/lib/control-center-2.0/gnome-settings-daemon'.
The one problem with this is that it starts the gnome screen saver, which I don't want. You can solve that problem by running gconf-editor, going to apps->gnome-settings-daemon->screensaver, and unchecking screensaver.
