[PyQt] How to compile SIP and PyQt using MinGW?

[chinakr]

Dear Phil and the kind guys here,

I recently want to use SQLCipher with my SQLite database.
I followed a guide to compile the driver using MinGW:
http://www.qtcentre.org/wiki/index.php?title=Building_QSQLITE_driver_with_AES-256_encryption_support_%28Windows/MinGW%29
But PyQt told my that it's built with MSVC and I should built the
driver with MSVC too.
I'm not familiar with MSVC at all, it seems too difficult for me to
complete the task.
Now I have a new idea that maybe I can compile SIP and PyQt with
MinGW, so my driver built using MinGW can be used directly.
Can you help me? Thanks a lot!
