Does anyone know if it exists a Web IDE allowing to develop web application directly from a web application? The W3School website allows to write small piece of code in HTML or javascript but is there another solution more project oriented?

Well, it is easy to build an HTML editor. Here is my quick sample on phpe:
<form method="post">
<textarea id="editor" name="editor" style="width:100%;height:200px;"></textarea>
<input type="submit" id="btnSubmit" name="btnSubmit" />
</form>
<hr />
<?php
if (isset($_REQUEST["btnSubmit"])) {
echo $_REQUEST["editor"];
}
?>
Well, beware of attacks!

Do not forget good old Zope, providing through-the-web development for many years (Parts of Zope have been open source as far back as 1996, with the whole application server open source since 1998).
What is Zope?
Zope is an open source web application server primarily written in the Python programming language. It features a transactional object database which can store not only content and custom data, but also dynamic HTML templates, scripts, a search engine, and relational database (RDBMS) connections and code. It features a strong through-the-web development model, allowing you to update your web site from anywhere in the world. To allow for this, Zope also features a tightly integrated security model. Built around the concept of "safe delegation of control", Zope's security architecture also allows you to turn control over parts of a web site to other organizations or individuals.
