If you quote it therwise no,it is is its value which is passes as a
string. Just do (pack (button '.b :text (vector 1 2 3))) to see that

I don't really understand your question here. What data structure do
you talk here? If you want to add an option environment to a widget,
yes you have to modify it a little bit, but the Tk configuration
routine knows how to manage environment. Look at the code of
tkButton.c for an example of that. I can help you her if you need
that. But perhaps I have not well understood your question.
