Replying for anyone else who stumbles across this thread (almost) 20 years later...

I got TextColor to work on a RadioButton by creating a subclass and calling SetWindowTheme(SELF:Handle(), "VO", "VO") in the Init() of the control. I don't know what the relevance of the strings are, but anything other than blank seems to work. I think I'm basically linking the control to a non-existent theme.

As suggested earlier in this thread, DisableTheme() didn't help nor did calling SetWindowTheme(SELF:Handle(), "", "").

If you are just seeing a white box after making that change, you've probably done what I did and have white text on a white background. I wasted an hour or so figuring that out. :(

Credit goes to this thread for making me think that it should work and keeping me chipping away at the problem until it worked: https://stackoverflow.com/questions/31854015/changing-win32s-radio-button-text-color
As it turned out, only the SetWindowTheme call was necessary.
