Is it possible to use FM radio WITHOUT internet connection or special devices ?

On my Android phone, I can plug in the headphones, which are in turn used as antenna.
Since Android is Linux and Ubuntu is also Linux, it should be possible to do this on a plain old Ubuntu notebook (13.04), too. Is it ? Or does it need special FM-receiver electronics ?

If yes, which application can I use for FM-Radio ?

I repeat: Live FM-Radio WITHOUT internet connection at the time of listening.
