the application has a JFrame menu bar with menu items as login,
customer, and transaction.

customer has three pop-up menu items namely government, corporate &
individual.

transaction has two pop-up menu items namely deposit check, withdraw
cash.

when i click on login a dialog box should pop-up within the JFrame
asking for user's id and password, the user can be either a teller,
manager, sys admin.

once the authentication ( by validating the user credentials with MySQL
server bank staff database) is done, a MDI type window pops-up with
text box for entering the type of customer, text box for organization/
individual's name, address etc. or enter a new customer info. and store
it in MySQL database.

then clcik on transaction and proceed with a similar GUI and  conduct
the transaction and update the database.

i don't know if JFrame is the way to go or ?

would help if someone provides some source code.
