I'm building such a tool myself [0] and I've been gathering similar tools for some time now - you might find those two especially useful for your use case:

Where are you in terms of your development?
From the GitHub repository (I should copy this information to the actual documentation as well):
> The project is under active development. While it is live already, I consider the status late alpha due to possible changes and the minimal amount of widgets.
That said, it is an on and off project for me. A type of a playground for testing out things, but one with a long-term goal nonetheless. During October, several people contributed (Hacktoberfest), so my motivation went up again.
If you think this is the tool you would like to build your idea on, feel free to reach me (email or twitter) or join the project's Gitter [0].
