Need to create a IDE with xml interfaces.

We are trying to build a stand-alone Rapid Application Development (RAD) application that enables software developers to graphically build and deploy Services for a particular domain.

It will allow application developers to create, modify, debug  and deply applications.

It will be a complete IDE with editor having full support for drag-drop our specific set of components, users being able to create new components, wysiwyg features, source editor, templates which can be customized, wizards, database integration etc. All these underneath would generate ASP code, in addition to whatever files are made. Example, it'll allow the user to drag and drop DB connections and create Apps that talk to DB. Now, the application configuration files i.e. the engine, UI settings (toolbars, menu bars etc.), component interfaces, database layer which connects seamlessly to all data sources etc. will all be xml interfaces.

I am trying to find out if xml resources close to this (for application configurations and database connectivity) exist in the public domain. Maybe even with  limited set of functionalities for now.

Thanks,
Rashida
