If you mean to highlight the selected button out of the groyp.. Yes you can do it using the CSS and JQuery..

use the below snippet...

 <style>
    .listbtn {
        border: 1px solid #bbb;
        border-radius: 2px;
        background-color: #eee;
        text-decoration: none;

        width: auto!important;
        padding: 3px;
    }
    .selected {
        background-color: #222;
        color: white;
    }
</style>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
    $(document).ready(function () {
        $('.listbtn').click(function (e) {
            e.preventDefault();
            $('.listbtn').each(function () {
                $(this).removeClass('selected');
            });
            $(this).addClass('selected');

        });
    });
</script>

I am a little confused. But the code to enable a button would be something like. Button1.enabled=false; if(checkbox.checked) { Button1.enabled=true; }
