Well you can always use a QTimeLine and call resize(w, h) on the window. Might not be pretty though.

for setting the shape use QWidget::setMask();
you could fade in the widget . Use QWidget::setOpacity() for this.

Not that I encourage using private parts of Qt, but notice this wiki article: Fade and scroll effects.
