The beauty of pyGTK and Glade is they have opened up cross-platform, professional-quality GUI development to those of us who'd rather be doing other things but who still need a GUI on top of it all. Not only does pyGTK allow neophytes to create great GUIs, it also allows professionals to create flexible, dynamic and powerful user interfaces faster than ever before. If you've ever wanted to create a quick user interface that looks good without a lot of work, and you don't have any GUI experience, read on.
This article is the direct result of a learning process that occurred while programming Immunity CANVAS (www.immunitysec.com/CANVAS). Much of what was learned while developing the GUI from scratch was put in the pyGTK FAQ, located at www.async.com.br/faq/pygtk/index.py? As a metric, the CANVAS GUI was written from scratch, in about two weeks, with no prior knowledge of pyGTK. The Cross-Platform Nature of pyGTK For these reasons alone, pyGTK might be your choice.

Ajax (programming) Ajax is not a single technology, but a group of technologies. HTML and CSS can be used in combination to mark up and style information. The DOM is accessed with JavaScript to dynamically display, and allow the user to interact with, the information presented.

In 1998, Microsoft Outlook Web App team implemented the first component XMLHTTP by client script. Google made a wide deployment of standards-compliant, cross browser Ajax with Gmail (2004) and Google Maps (2005).[6] The term "Ajax" was publicly stated on 18 February 2005 by Jesse James Garrett in an article titled "Ajax: A New Approach to Web Applications", based on techniques used on Google pages.[1] get-ajax-data.js: send-ajax-data.php: jQuery example.
