Getting rid of 'minimize' and 'close' buttons.

I'm writing an application for my business in which as soon as the computer turns on the interface automatically runs, fills the entire and allows the user to pick an application to run from a list. However, I don't want the user to be able to close or minimize my interface without putting in a password. How can you make an interface so that the 'minimize' and 'close' buttons are not present, and the only way to close the interface is by putting in a password in a JPasswordField?
