I think it would be preferred to use KDE functionality in this case. Why pass 
by KDE and Qt and go directly to X11 to do that? That would also mean that you 
would have to take into account that KDE and Qt run on different platforms 
that handle keyboard layouts differently.

You must abide by separation of concern. In your application your concern is 
to determine wether a particular applet is running. It is NOT your concern how 
that fact is asserted. If it is necessary to add functionality to be able to 
let others determine if you are running so be it - then add that functionality 
to the applet either by letting the applet expose something over DBUS or by 
any other means necessary and add that to KDE and/or Qt.
