If one goes back a few years it was common for a distro to ship GNOME and KDE, even on a CD. Of course I'm talking RedHat 6.x when everything was a heck of a lot smaller. It was the growing size of everything that forced a one cd install image to pick one or the other. Just squeezing in Qt isn't a big deal though, try making a cd with all of KDE and a base GNOME + OpenOffice.org + Firefox/Iceweasel. Good luck. Any DVD based install will give you both though.
