I decided to throw together a GUI version of the stand-alone builder. It requires .Net Framework 4, of course.
It should be a bit easier to use as there are less options and no command-line arguments to deal with. The output is still directed to a text box so you can see what's going on and deal with errors.
Interfaces are not my strong suit, so any suggestions are welcome
The source is available at the same place as the original,
https://code.google.com/p/xray-builder/, under the "gui" repo.
I rushed through the readme file so it may not be entirely clear.
Let me know if there are any issues with it. It seemed to work fine on my system, but I haven't had a chance to test it in any other environments yet.
Latest version will be in my most recent post in the thread.
