Creating a banner+message overlay on bottom of window

I want to display important messages via a red banner that can appear/dissappear at the bottom of the window, which persists across all QStackedWidget windows. How would I go about doing this? I've created a rough illustration of what I want:

You can make use of http://doc.qt.io/archives/qt-4.8/qstatusbar.html#details.

@Ratzz please use the latest documentation links. Qt 4 has already reached end of life for some times now.
