qxdotnet
qxdotnet is a server side ASP.NET wrapper for qooxdoo library
...It is not comfortably. The main qxdotnet idea is a creating C# mirror objects for qooxdoo UI controls. State of the objects on the server and the client is synchronized with AJAX. For example, you just create a C# "button" control and place it on the form. After you start your ASP.NET application, you can see the button inside browser.
