JFrame which does not allow resizing (maximizing, minimizng)

Question

I want to develop a login frame which does not allow resizing (maximizing, minimizing as this does not make sense) and with 2 fields, JTextField and JPasswordField.
The frame is developed but has the usual resizing handles.
How to do?
Many tks for any information.

Don't use a JFrame. Also, don't expect code like this again; I did it for fun.
It requires your modification.
