Pleasure,
we are a few guys interested in this project, how could we help ?, is
there a project roadmap or something ?
as soon as QtAda can be build with the Debian default GCC, i would be
pleased to participate creating the QtAda Debian package for all
Debian family Linux ...

For now, i'm working on a Ada Designer tool application, so i wrong be
available for a 1 months ...

Do you mean i must create this file with a Qt tool like QtDesigner ?
because creating an empty file named hello.ui does not work

$ ls
hello  hello.adb  hello.ads  hello.ali  hello.o  hello.ui  Makefile
Makefile.am  Makefile.in
$ ./hello

Execution terminated by unhandled exception
Exception name: CONSTRAINT_ERROR
Message: qt4-ui_loaders-impl.adb:90 access check failed
Call stack traceback locations:
