Making a classic Windows 7 widget

[MadRey]

The first time i heard about QT widget i was hoping to be able to make something like the classic windows 7 widgets.
That means i was hoping to make something like a clock from the examples but without a window border and just a round frame.
I only just started to learn QT so i'm not even really sure what to use between the two.

All i could find so far was how to make the whole window invisible with children and all.

setWindowOpacity(0.6);
    setStyleSheet("QWidget{background: #000000}");
