Probably not possible:

I have an EmployeeMaster table which is the source of a layout in form view. I would like to have a portal in the bottom of the form view that lists the Employees. In addition, and when a find procedure is used, it would list the found set.

Since the EmployeeMaster is the main table and not available as a related table, the EmployeeMaster table cannot be used in a portal. Is there one of those exotic tricks that exists to accomplish this task?

You can certainly relate a table to itself. This is known as a 'self-join', and is very common. You just need to use another occurrence of the same table on the relationships graph.

It's also possible - though not quite simple - to reflect the found set in a portal:

However, I think in this case you could do something much simpler -see:
