This is also in the documentation somewhere and applies for any class,
not just GstBuffer:

*** GstBuffer* -> QGst::BufferPtr: Use the wrap() method.

GstBuffer *buf;
QGst::BufferPtr qbuf = QGst::BufferPtr::wrap (buf);

*** QGst::BufferPtr -> GstBuffer*: Just cast to the C class pointer
(static_cast, to be sure it is safe)

QGst::BufferPtr qbuf;
GstBuffer *buf = static_cast<GstBuffer*>(qbuf);

Regards,
George
