It is possible to avoid forward declarations by a proper function rearranging.
Also please add 'const' to classA/W.

10 should be enough.

'static const CHAR BUILTIN_CLASSES[][10]' as in the existing test would be
better IMO.

You forgot "ScrollBar" and some other builtin classes.

MultiByteToWideChar would be more appropriate here.

It would be helpful to actually test whether window has been created, and what
type it has (ansi/unicode). Same is true for all similar cases.

Otherwise the test looks good, and it passes for me under XP SP3.
