No, it uses GET verb for GetCapabilities, DescribeFeatureType and GetFeature.
It uses POST for the transactional part only.

But it is not difficult to translate your POST feature request into a GET one.
Or you can use your existing code to download the GetFeature response and use 
the resulting GML file as the input of ogr2ogr.
