XFCE starts the `xfwm4' window-manager.
You can switch manually after the fact by doing:
killall xfwm4; ctwm&
from an xterm (you may have to do it a couple times, since there's
a race condition between ctwm and the session manager which tries to
immediately restart a new xfwm4).
Or you can arrange to have a script called ~/bin/xfwm4 which runs ctwm
(so as to trick XFCE into starting ctwm when it thinks it's starting
xfwm4), such as the one below.

#!/bin/sh

# Fake xfwm4 that really calls ctwm.
#
# xfce4-session has $HOME/bin early in its path, so placing this script
# there will override the real xfwm4.
# Typically called by xfce4-session as
# xfwm4 --replace --display :0.0 --sm-client-id
