Not with a wxRadioBox.  It automatically chooses a default for you.  Have
you thought about adding another option at the top saying "Please pick
one"?

Actually, it IS rather uncommon.  Folks would often forget to make that
default choice when using radio buttons, so the designers of wxRadioBox
made it automatic.

Yes, that's another option.
