Rule of thumb: always test your code snippets before posting them. We
often can't fix problems if we can't duplicate them.

Exactly as you show above (without the trailing question mark)

     $w.text insert end $string d1

That absolutely will work. If it's not working you're omitting certain
facts. Either "$string" contains the value "$string", you're putting
curly braces around the $string, or there's something else weird going on.

My suggestion: start in a fresh interpreter and type in the following code:

     set w ""
     text $w.text
     pack $w.text
     set string "le mie vane parole"
     $w.text insert end $string

You should see "le mie vane parole" show up in the text widget. That
proves the above code works. Now the trick is to figure out how your
code is different from the above code.

It would really help if you could show your actual code in a way where
we can reproduce the problem.
