Just saw this on the ParaView Mailing List, MIRARCO has released a Wizard system to accelerate development of ParaView Plugins. Simply answer a few questions and it will create C++ Templates, an XML file, and the necessary CMake file to build it.  Then just fill in the blanks.

Plugin Wizard is a free, GPL/OpenSource application developed by MIRARCO. Developed using Python and Qt (PyQt), Plugin Wizard will allow you and your developers to save incredible amounts of time when creating your Paraview plugins.
