title: ExtJs Vs Ext GWT Vs SmartGWT
body: <p>I am going to start a new application which mainly consist NavigationPane, Grid, Toolbar. Layout should look like this demo page <a href="http://www.gwt-ext.com/demo/" rel="nofollow noreferrer">http://www.gwt-ext.com/demo/</a></p>
  
  <p>I am quite confused which one to use in terms of writing less code, more performant, etc..
  Could someone tell the pros and cons of all these technologies.</p>
  
  <p>All the while I coded in javascript, so that way ExtJs seems to be the easy one for me to code. But I am curios to try GWT Ext, Is it true that it could do a lot just by writing few lines of java code. </p>
  
  <p>For eg: To achieve the layout ( given in  above gwt ext demo url), which one should I opt ExtJs  or GWT Ext.</p>
  
  <p>I read SmartGWT is relatively slower than GwtEXT. Does it have any advantage over GWT EXT. I am also looking for hibernate based data modules ( as my application is going to have many database calls). Anyone of SmartGWT or GWTExt has support for such modules. I came to know that smartgwt doesn't offer all of smartclient enterprise version functionalities, that we are allowed only a few of smartclient features. Will it be an issue?</p>
  
  <p>Your response is highly appreciated.</p>
