Once.. I tried to create this, but It was not pretty. I listed all the things I need to have on a page and increased the progress bar One by one as it was loaded. It was very tremendously long chain. Here is a sample of what I did.

$.getScript('js/lib/ui.js',function() { //Load the Jquery UI
    //Call back function after the loading is complete

    $("#progressinfo").html("Loading Widgets ..."); //Give the information 

    $.getScript('js/lib/widget.js',function() { // Load the jquery ui Widget
    //Call back function after the loading is complete

        $("#progressinfo").html("Loading Widgets: Progress Bar ..."); // Inform

        $.getScript('js/lib/widgets/progressbar.js',function() { // Finally load the Jquery UI progressbar
            //Call back function after the loading is complete

            $("#progressbar").progressbar({ value: 5 }); // change the value of the UI informing the total amount of loadding completion                                             
            $("#progressinfo").html("Loading Widgets: some script ..."); //Inform of another script

            $.getScript('somescript.js',function() { // Load another script
            //Call back function after the loading is complete

               $("#progressbar").progressbar({ value: 6 }); // change the value of the UI informing the total amount of loadding

            });
        });
    });    
});
