Interfaces if not out-of-box.

Visualforce is a framework that allows developers
to build sophisticated, custom user interfaces that
can be hosted natively on the Force.com platform.

design in Software Architecture.
Apex is a strongly typed, object-oriented
programming language that allows developers to
execute flow and transaction control statements on
the Force.com platform server in conjunction with
calls to the Force.com API. Using syntax that looks
like Java and acts like database stored procedures,
Apex enables developers to add business logic.
