You can simply add:

onClick="window.open('http://www.google.com/','mywindow','width=400,height=350')"

To any Anchor or Input tag, or just add this to the head of a file to open automatically.

<script type="text/javascript">
   window.open('http://www.google.com/','mywindow','width=400,height=350');
</script>
