Despite your negative tone, I think you have a point. There are many project like this. I'm working on another one at the moment and I have compiled a long list of similar projects. There is definitely a need for a tool that can create UIs visually. IMO such a tool needs to have interoperability with code, as in changes to the code reflect in the tool and changes in the tool make reflect back in the code.

We haven't succeeded in creating an intuitive and robust enough tool that accomplishes this, but that doesn't mean that it's impossible. It's a technical challenge which can be overcome.
