I recommend using jQuery as it will do all the heavy lifting for you. The code is fairly trivial.

$('input:checkbox').click(function () {
  if ($(this).is(':checked')) {
    $('#sendNewSms').click(function () {
      return false;
    });
  } else {
    $('#sendNewSms').unbind('click');
  }
});

The trick is to override the 'click' event and effectively disable it. You can also follow it up with some CSS magic to make it look "disabled". Here is the code in JavaScript in case you need it. It's not perfect but it gets the point across.

var clickEvent = function () {
  return false;
};
document.getElementById('#checkbox').onclick(function () {
  if (document.getElementById('#checkbox').checked) {
    document
      .getElementById('#sendNewSms')
      .onclick(clickEvent);
  } else {
    document
      .getElementById('#sendNewSms')
      .removeEventListener('click', clickEvent, false);
  }
});
