Hmmm not sure what exactly "components" means.  Are those dbus services?

I'm not a KDE user so I have no idea what kind of runtime infrastructure KDE 
requires.

Also, the display manager is the part which allows users to login, right? 
That's (supposed to be) independent of the desktop environment in use.

Check out gnu/services/desktop.scm elogind-service-type for a more involved 
service.

It uses the service extension mechanism to extend other services.

You might want to use that mechanism to extend dbus-root-service-type in 
kde-service-type in order to add dbus kde stuff (if any; no idea).  You can 
also extend shepherd-root-service-type in order to add shepherd services.

The display manage I use is managed by slim-service-type (see also 
%desktop-services where it defaults to slim).  It looks for desktops that it 
can start in /run/current-system/profile/share/xsessions .  If you put a KDE 
package which provides desktop files in share/xsessions to your /etc/config.scm 
"operating-system" "packages" form, a new entry will show up in SLIM (press F1 
key).

In the case of xfce, xfce-service-configuration refers to the package "xfce" by 
default.  This package does an union-build of many other packages, including 
xfce4-session, the latter of which is the one installing the desktop file into 
/run/current-system/profile/share/xsessions .
