As far as I know AJAX is the only solution apart from the other two
things you mention-- delivering the whole page again or using frames.
The only way to update part of a document from the server while leaving the
rest of it there is to use AJAX.
Another alternative is just to write the mortgage calculator in
JavaScript (or, less popular these days, in a Java applet) instead of
C++. Then it can run on the user's machine, saving you CPU cycles and
carbon credits.
