The solution I can think of is removing the panels Available and Inactive Widgets so there's simply nowhere to drag (and delete) the widgets used in the sidebar. And you

You can inject something else to fill the gap.

Important: the HTML; closing line cannot have any white-spaceswhitespace characters before or after

PS: this Heredoc sintaxsyntax <<<HTML code HTML; is preventing the code to display the PHP properly formatedformatted here in WPSE. But the code is tested and working.

In mythis example, only one user is able to add/delete widgets.

Don't know why, but setting display:none was not working via CSS to hide the widgets descriptions, so was done in jQuery.

function wpse_53398_script_printer(){
    // used to display the front end site
    $site = get_site_url();
    
    // here you can filter who can add/delete widgets
    global $current_user;  
    if ( 'kursus' != $current_user->data->user_login ) 
    {
            echo <<<HTML
            <!-- CSS to hide the widgets descriptions = real estate gains -->
            <style type="text/css">#widget-list .widget-description {display:none;}</style>
            <script type="text/javascript">
