There is PyQt Visual Modeller for R package (i.e. Red R) which is sort of derivative of Orange.
Red R http://www.red-r.org/ Orange http://orange.biolab.si/features.html This is similar to ArcGIS Model Builder. The beauty of Red-R and Orange is uses python and Qt (i.e. PyQt), so I can be easily adapted for QGIS instead of using WxPython which Grass use.
