You're executing your JavaScript before the elements exist. Either move your code to the end of the page or put it within an onload handler.
Ex:
<!DOCTYPE html>
<html>
<head>
<title>dice app</title>
</head>
<body>
<button id="button">Roll Dice</button>
<script src="widget.js"></script>
</body>
</html>
