Question : How can I allow user to modify the interface of the application (Visual Studio)?

How is it possible to allow user to modify the interface of the Visual Studio (C++ or C#) application (after running it)? I would like to make it possible for him to - for example - move buttons in the window. Is there any component for that? It should work similiar to the Dialog Editor in the Visual Studio.
The component doesn't need to be free.

        {
            drag = false;
        }
