To my experience, to be able to successfully finish a large project, you normally should be able to imagine in detail what you want to create before you even started coding. I.e. if you can draw on paper desktop environment you want, and imagine in detail how every part of it behaves and interacto with users, then you'll be able to make this product very quickly. If you can't imagine in your head, how it should behave, then you have a problem. If you're "looking for ideas", this may indicate that you don't exactly know what you want to get, and simply want to make "better KDE". Without clear idea, a project will either take 50x more time to materialize, or will never be finished. "as easy to use as possible" is a very vague goal (define "easy", for example) for a successful project.
Furthermore, there is already C++/Qt 4 desktop environment, and instead of making new environment from scratch, it might be a better idea
to fork KDE4, tear it apart, strip down functionality, tweak it and turn it into environment you want.
Also, I wouldn't approve working on(or asking anybody to work on) any project for free (a work should be rewarded), but that's personal preference. Instead of looking for like-minded people, it might be more efficient to accumulate some cash and hire people to code for you.
Just my 2 cents.
