From the Phonegap side, you could attach a handler function to the backbutton, something like this:

function exitApp() {
    console.log("Exiting app");
    navigator.app.exitApp();
}

function onPressBack(e) {
    e.preventDefault();
    navigator.notification.confirm("Are you sure you want to quit?", function(result){
        if(result == 2){
            exitApp();
        }
    }, 'Quit My App', 'Cancel,Ok');
}

function deviceready() {
    $(document).bind('backbutton', onPressBack);
}
$(document).bind('deviceready', deviceready);

If you're using jQuery Mobile for paging, you can keep track of whether it's the first page being shown and therefore whether to show the exit dialog - see my answer to this question
