How to create a modeless dialog in Perl / Tk?

Question

I am learning Perl / Tk. I want to inform the user when he / she receives mail.

I planned to use the message box in Tk, but it expects the user to click ok or cancel.

Until the user clicks a single button, he will not perform any further operations.

But I want, he just needs to give a warning to the user, and the user can continue the further process.
