In modern Kubuntu there is an Info Center app which you can find in K menu -> Applications -> System -> Info Center or start from console using kinfocenter. It shows Plasma version, Frameworks version, Qt version and other useful info.
Start any "standard" KDE program, such as Konsole or Kate and select Help - About KDE
If you want to do the same from the command line, you can invoke any "standard" KDE program with --version (or -v) parameter. The program then will print the version and exit:
# kate --version
Qt: 4.8.6
KDE Development Platform: 4.14.2
Kate: 3.14.2
# konsole --version
Qt: 4.8.6
KDE Development Platform: 4.14.2
Konsole: 2.14.2
# plasma-desktop --version
Qt: 4.8.6
KDE Development Platform: 4.13.3
Plasma Desktop Shell: 4.11.11
