How should I start creating dynamic futuristic GUI-s in Qt?
Like this:


Or like this Altia GUI demo:

I've seen the following library, but it's anything but modern.

Should I do Photoshop/PNG slicing? Or OpenGL 2D?
I would like the best GUI for my customers, with short developing time.

(I've just started using Qt & already done a lot of searching)
Thanks,
