It's pretty complete and stable, we are using it for our production. Gtk2 does 
not have chance with our needs.AFAIK you already seen our erp app at lazarus 
day last summer, it's qtlcl app :)
Minimum required qt version is 4.5.0, but if you use old KDE installations, 
probably you have to build it by yourself. If you want I can send you rpms 
maded for older distros (Qt-4.6.4).
