you haven't instantiated an intensityWindowing object....I don't see it 
in your definitions above...

typedef 
itk::IntensityWindowingImageFilter<InternalImageType,InternalImageType> 
IntensityWindowingFilterType;

IntensityWindowingFilterType::Pointer  intensityWindow = 
IntensityWindowingFilterType::New();

then you can connect it to the gaussian smoothing filter...
