Aka cdesktopenv is a vintage desktop environment.

Enabling

 
/etc/nixos/configuration.nix
  services.xserver.desktopManager.cde.enable = true;

Changing fonts

 sudo mkdir -p /etc/dt/config/xfonts
 sudo cp -r ${pkgs.cdesktopenv}/opt/dt/appconfig/types/C /etc/dt/config/xfonts
 sudo cp -r ${pkgs.cdesktopenv}/opt/dt/appconfig/types/en_US.UTF-8 /etc/dt/config/xfonts

Now edit /etc/dt/config/xfonts/*/fonts.alias and remove all -dt-interface references. Add these instead. In this example Helvetica and Courier are used instead of fixed fonts.

Adding programs to autolaunch

 
~/.dt/sessions/sessionetc
 autorandr -l docked
 xcompmgr -c &
 chmod +x ~/.dt/sessions/sessionetc

Editing panel

 cp ${pkgs.cdesktopenv}/opt/dt/appconfig/types/C/dtwm.fp ~/.dt/types
 chmod +w ~/.dt/types/dtwm.fp

Now edit ~/.dt/types/dtwm.fp

To disable system control, add a delete property like this

 CONTROL Trash
{
 CONTAINER_NAME  Top
 CONTAINER_TYPE  BOX
 DELETE          True
}

Creating an own program icon

Use Desktop_Apps/Create Action tool. Save actions under ~/.dt/appmanager. Save icons under ~/.dt/icons

The icons must be in XPM or XBM format and they need to be in three sizes: 48x48, 32x32 and 16x16. Create three separate icons as each will be "consumed" when you use them in Create Action. I used The Gimp to create the three icons I needed. Examples are under ${pkgs.cdesktopenv}/opt/dt/appconfig/icons/C
