I do not. But I assume that something that was designed to power a website might not be perfectly suited for writing a "client" application out of it. Perhaps it's aimed at experienced professional developers so it's not very straightforward to use, perhaps it requires the installation of a bunch of other server software that would make any self-contained final app very large and it may not be possible to integrate everything into a single executable, perhaps it would take a fair amount of extra work to integrate it with a GUI because it's not really designed for that. I would be happy to be informed that these assumptions are incorrect.
