If you don't want to use CW_BGROUP and widget_control, GET_VALUE=,
it's probably easier to just maintain toggle flags for the state of
each button, and update the flags in your event handler. I usually
use these flags for other purposes anyway.

Uh, no. Usually the program already knows what the buttons say!
