Correct (for Solaris ---  -t WS_WIN for Windows).

You need -I <directory where PyQt sip files are>

add 

%Import qtmod.sip

after the %Module statement. sip needs to see .sip files that
resolve everything back to C++ base types (the same as C++ would
need to see the entire object hierarchy to compile), so it needs to
see at least qwidget.sip and qobject.sip, plus anything else
QWidget depends on in Qt. You could also just %Include the PyQt
.sip files you need if it's only a few (instead of importing all of
PyQt) - that may be a little more complicated than it first
appears because of versioning/platform/features requirements.

sip will generate .h files for all of the Qt sip files in
your output directory, but no additional .cpp files. You'll also
need to link to libqtcmodule.so and libsip.so (in
python/site-packages on Linux), which is why you need the PyQt
.h files. I can't advise you on what Windows requires since I
don't use it, but it's basically similar.
