This has been rehashed 20 times already, so quickly a few notes:

1. Boolean gadgets with text only cannot be updated as you mention. They
should have a bitmap associated, instead.

2. The usual way of doing this is to RemoveGadget, modify it, AddGadget,
and RefreshGlist (or RefreshGadgets)

Take a look at some source code that does "mutual excluded gadgets".
