Hi, Jason.

Welcome to Neutrino. Here are some answers to your questions:

You can use PhAB (the Photon Appbuilder) to create graphical
applications that use the Photon microGUI. You lay out the user
interface, and PhAB generates the code that creates the UI and pieces
that you can attach the rest of your application to. PhaB runs on
Neutrino, but there's also a version that runs on Windows.

You can also use the IDE to create applications (graphical or not), but
it does a lot more too. You can use the IDE to build a boot image,
download applications to a Neutrino target machine and run them there,
profile your application, profile the entire Neutrino system, look for
memory errors, and more. You can even use the IDE to start PhAB on
Windows to develop a Photon application.

In 6.3.2, the Neutrino version of Momentics includes a runtime Neutrino
system (i.e you get the OS, Photon, and the development tools). On
Windows and Linux, Momentics is a development system that you can use to
create programs to run on Neutrino (on a separate machine or in a VMware
session).

That's right. The Neutrino Host installer will create a new partition on
your Windows machine and install the Neutrino OS and the Momentics tools
there. If you want to run the IDE on Windows, you'll also need to
install the Windows Host version of Momentics.

I hope this helps.
