create a QGraphicsScene
create a QGraphicsView
attach it to the scene
create a QGraphicsLineItem
add it to the scene
create a node (QGraphicsRectItem, QGraphicsEllipseItem, or what you want)
give him the line item as parentItem
position it at the end of the line item
...
have a look at examples/graphicsview/... examples
and QGraphics* classes documentation
