QT Applications
I used to think of QT as primarily a Linux GUI library used primarily by KDE with grand ambitions toward Windows and other desktop environments. Now, there seem to be hundreds of QT applications on Windows, presumed some of them stable and mature.
Not only that, but pyQT may be slightly easier way to develop cross-platform applications .... times have changed.
Still vague on the details.

Emergent
Jan 2017: very technical environment, but I'm making closer inspection. Project is active and has a fairly large community - looks useful for dealing with large 'signally' data sets and monitoring dynamic streams ( i.e. data fusion ). See Devices.
http://en.wikipedia.org/wiki/Emergent_%28software%29
Emergent (formerly PDP++) is neural simulation software that is primarily intended for creating complex, sophisticated models of the brain and cognitive processes, but can also be used for any task to which neural networks are suited.

Good coverage of dependencies, useful things to have for Windows particularly.
