title: Rich Internet Applications with ExtJS: Which direction should I choose?
body: <p>I need some help in choosing the right way for my RIA. I do want to use a javascript widget library - possibly ExtJS. I'm not sure however if I should try to get around programming in Javascript through <a href="http://extjs.com/products/gxt/" rel="nofollow noreferrer">ExtGWT</a> or other solutions like <a href="http://rialto.improve-technologies.com/wiki/python" rel="nofollow noreferrer">Rialto Python</a>. What are your experiences with web application frameworks that do not require you to program in Javascript? For instance, is it a big disadvantage to abandon technologies like jQuery if heading for GWT?</p>
