There is no direct way to do such a thing that I know of.
However, you could easily code yourself a little function that would get 
your widget's subwidgets (with the .children() method) and filter out 
the non-QLabel ones:

def getChildrenByType(obj, type):
  children = obj.children()
  isTypeSuitable = lambda child: child.isA(type)
  return filter(isTypeSuitable, children)

for child in getChildrenByType(self, "QLabel"):
