A WEB front end will solve the problem that they do not necessarily

OK, SSL for data encryption and "strong authentication" shall be
called into service ...

For traffic encryption SSL. For authentication I would go with
ID Cards (those with an LCD Display that changes every minute).
They do not require an interface with the system (which could
be any kind of system you said before...) and are reasonably
priced.

Do not forget that your application should be able to disconnect
idle users and leave nothing in the clear on the client PC (since
it is not necessarily owned by your user).
