In KDE 4, it's like so:

shell:~$ xhost +local:
(only once)
shell:~$ at 10am Feb 8
at> export DISPLAY=0:0
at> qdbus org.kde.knotes /KNotes newNote RememberThis "Remember your
anniversary, you putz."
at> ^D

...KDE 4 and recent GNOME use qdbus (command-line) and qdbusviewer (GUI
explorer) for telling various GNOME and KDE apps to do various things. 
AFAICT, the vast majority of interesting/useful stuff is done through
org.{kde,gnome}.APPNAME /AppName (various commands).  It's sorta complicated,
but it rewards some study and fiddling with, in much the same way that DCOP
did with KDE 3.
