In case you're not aware: CDE is still around, open source, and runs on modern unix-likes.
There is also a FWWM[1] "skin" that doesn't require long time abandoned C code - NsCDE[2]. It still requires X server (just like CDE itself) which becomes rarity these days. They need to port it to Wayland eventually.
