I doubt you'll find any software to actually CREATE a CRW file, and it certainly
won't be IrfanView. You can obtain a developer's kit from Canon that should
contain the info you're looking for on the data structure, but you'll probably
need to write your own software to do what you want.

All RAW files out of cameras are essentially just a straight data dump from the
sensor... there's no real need to generate such a camera-specific file outside
of the camera.

Hi Matt,
The problem is that I need the raw data to be specific data. I need
the raw data to represent a perfectly neutral image - like a gray
card. I do not want to photograph a gray card because it is the light
that I am trying to control. I bet Canon has a reference gray raw they
use for testing but I do not know how to get it.

Thanks,
Ron

Is this what you're trying to do:
Import a true neutral image into the camera, then use that as a
comparison to other shots you take, white-balance-wise?
If so, shooting in RAW wil llet you adjust white balance easily, so
this shouldn't be necessary.
If not, drive on... :-)
