I don't think this is possible in QGIS 2.0. (We already had this question in 2011 - just without the Python aspect: Polygon gradient fills / tint bands in QGIS)

For the next version, a gradient fill has been announced by http://nyalldawson.net/2013/09/sneak-peak/:

enter image description here

This is the responsible class: http://www.qgis.org/api/classQgsGradientFillSymbolLayerV2.html and there seems to be an option to let the gradient start from the center of the polygon:

setReferencePoint1IsCentroid (bool isCentroid) 
Sets the starting point of the gradient to be the feature centroid

@Vassilis then I suggest to get on the bug tracker and discuss it as a new feature request.
