The only thing Qt Creator needs at the moment from PCSuite/OviSuite is the device driver.
Which is probably also available independently.

The advantage of using OBEX would be the faster upload though (some factor 7 or 8 afair).
I had a look at PCCAPI and hesitated to pursue that further since it is pure Windows API, plain OBEX would probably be easier to port+maintain in the future.

The funny part is that if you happen to have PCSuite installed (and most probably running), it blocks the OBEX channel. No idea if this is different for the PCSuite connectivity API.
