We already have a javaforge site, but it kinda fell into disuse.

after you crete an account I can add you to the project, it's a mercurial repo. I tried git but couldn't make it work. mercurial is more newb friendly 
I uploaded an updated version of the gui to the repo. I made some small tweaks, embeded fonts not done yet, but I included the fonts.
@arclance, I added an option to change the builtin style, tryout the different ones to see which work the best. it's at the top of masterwork_launcher.py3 , feel free to try out stylesheets if you want as well, they should work on all platforms.
I created an account on javaforge, username arclance.
I have never use mercurial to do anything but clone a repository before but it should not be a problem.
I looked at the code for masterwork_launcher.py3 and I see a couple of problems with the style changer.
1. "Macintosh" should not be the default since it is not cross platform.
You will just get a lot of "It crashes on windows" bug reports if you leave it like that.
2. You are missing the GTK+ style it is what lets you use your GTK theme in QT on linux.
I tried stylesheets in QT Designer before, that was the only way to override the system theme for buttons.
There were some problems though, I could not get all the colors right using the system theme.
I could not set the font color of QComboBox objects or do anything to the tabs when using a system them, it works with the others though.
Hardcoding the colors seems to work as long as you don't use a system theme (ie. mac, windows, or gtk+) at least with the preview option in QT Designer.
I need generate the python code first to test if it really works.I tested this by backporting your changes to the old script so I could test it.
Works okay but not with GTK+, the tabs won't change at all.
Edit:
Here is a mainframe.ui where I hardcoded the colors and added a minor stylesheet.Let me know how those changes work for you.
The tabs probably won't accept the colors with the Macintosh theme, try some of the others as well.
I may make some changes to this now that I now things work better when running the actual python code.
I would like to do this again from scratch using the font that will be in the final version to see what is necessary and what is not.
When do you think you be done getting the font embedded?
