    The safest way would be to actually initiate this from the client side. 

ie. ssh -X webserver xcalc

    Assuming xauth is all set up between the client and server, it might be
possible to do what you're talking about safely, but why would you want to?
Implement a calculator in javascript if you want to embed one in the page, or
download one already written.
