QListWidget has a lot of the drag and drop functionality already defined, so it is just a few features that have to be enabled:

class DragDrop(QtGui.QWidget):

    def __init__(self):
        super(DragDrop, self).__init__()

        self.list1 = QtGui.QListWidget()
        self.list1.setDragEnabled(True)
        self.list1.setDropIndicatorShown(True)
        self.list1.setDragDropMode(self.list1.DragDrop)
        self.list1.setDefaultDropAction(QtCore.Qt.MoveAction)

        self.list2 = QtGui.QListWidget()
        self.list2.setDragEnabled(True)
        self.list2.setDropIndicatorShown(True)
        self.list2.setDragDropMode(self.list1.DragDrop)
        self.list2.setDefaultDropAction(QtCore.Qt.MoveAction)

        self.list1.addItems(["Item%02d" % i for i in xrange(5)])

        layout = QtGui.QHBoxLayout(self)
        layout.addWidget(self.list1)
        layout.addWidget(self.list2)

If you redefine the dropEvent() method on the QListWidget then you will be able to emit a signal
