import sys

from PyQt4 import QtGui

class Widget(QtGui.QWidget):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self)

        self._label  = QtGui.QLabel('A Label')

        layout = QtGui.QVBoxLayout()
        self.setLayout(layout)
        layout.addWidget(self._label)

        self._button = QtGui.QPushButton('&Push Me', self)

    def paintEvent(self, event):
        w = self._button.width()
        h = self._button.height()

        x = (self.rect().width()  - w)/2.0
        y = (self.rect().height() - h)/2.0
        self._button.setGeometry(x,y,w,h)

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)

    widget = Widget()
    widget.show()

    sys.exit(app.exec_())

I will abjure any relation to this code..
