Hi Alice
GUI2PY doesn't has the "project" concept, to be as simple as possible, they are just python windows files (pyw) or resources (like pythoncard).
You can start a new one just by copying some of the current samples:
or
You can edit them just invoking the designer:
copy minimal.pyw myapp.pyw
python -m gui.tools.designer myapp.pyw
When you close the designer, the changes will be saved to the file.
I'll add proper support for rad2py (IDE) but that will take some time.
Best regards,
