It looks really professional. It's nice how you can do pretty, practical things with U++.
If the application is not too big, nor full of links to other libraries, perhaps it could be included.
However, perhaps more interesting would be to make one or more packages including function sets and classes that would be of interest to other developers, including sample packages to demonstrate how to use them.
In addition, the packages you include should be with the same license as U++.
