Creating a desginer in WebApplication
<p>I am planning to develop a small web application, which enable users to create small application according to their needs. The layout of the web page should be like visual-studio, where:</p>

<ul>
<li>The left pane contains all the
controls(I only provide few basic
controls like txt box, lbl etc)</li>
<li>The right pane contains the
properties of currently selected
control (again only few basic properties like color, font etc)</li>
<li>And the canvas lies in the middle of
page, where user drag and drop
controls and set their properties</li>
</ul>

<p>I am beginner, please guide me where to start and what resources to study. According to my knowledge i need to do some scripting (java script, JQuer, GWT). If that's right then what scripting languages should i use with ASP.net and C# </p>

<h1>Edit:</h1>

<p>I have experience of web application development but i never used scripting, <strong>so i only need guidance regarding scripting</strong></p>
