It depends on whether you want to do it on the j side or the Qt side. For the J side, it is simple, just uses wd and gl2 commands. For the Qt side, you need to subclass a QWidget and create a QPainter and also a QImage/QPixel if you want double bufferring. git-clone or browse the gtide git repo in particular the files isigraph* and gl2* under the lib/wd folder.
