Custom Display Manager in linux with Qt

[Sht1rlitz]

Is it real to make linux Display Manager via the Qt GUI project?
Or i have to drawing GUI by using the pure XLib instead?

Thanks for any answer!

kdm does use Qt AFAIK, so it is possible.

Thanks! Does XServer require be started to use Qt-based DM?

I am no expert there, but I think all X11 display managers require that there is a Xserver running. They are X applications after all.
