I think the easiest way to achieve this is to implement a custom QGraphicsEffect for rotation. You can then apply this to whatever widget you like and you can animate the rotation with QPropertyAnimation.

BTW: If you need a fancy interface use QtQuick. It makes such things much easier:

import QtQuick 2.6
import QtQuick.Window 2.2
import QtQuick.Controls 1.4

Window {
    visible: true

    Button {
        id: btn
        anchors.centerIn: parent
        text: "Exit"
        onClicked: Qt.quit()

        transform: Rotation {
            origin.x: btn.width/2.0; origin.y: btn.height/2.0; angle: 0
            SequentialAnimation on angle {
                loops: Animation.Infinite
                PropertyAnimation { to: 360; duration: 1000 }
                PropertyAnimation { to: 0; duration: 2000 }
            }
        }
    }
}
