I don't know, how to do this, but this iss annaunce of Fedora QtDesktop
spin.
It contains qt based applications only.
And those applications that required for installation into HDD.
It is based on my old kickstarts for F16 and F17 (minimal set - just
livecd-mini+slim+razoqt) and now requires loooong work for cleaning up
unwanted packages.
And adding mandatory/usual ones.

PS. My dream is to make Fedora and CentOS spins without any gtk*/*gnome*
library. Just for funs.
