Yes of course. There's also the newer Qt Creator program if you want to use Qt 5. The license of the Designer and Creator programs does not apply to the output of these programs (the .ui XML files). You'll want to read up on the documentation. Here's a couple of links for starters: http://doc.qt.io/qt-4.8/designer-layouts.html https://wiki.qt.io/QtCreator_and_PySide (works with .ui files from Designer also) Even if you don't use a GUI designer, you should construct your GUI with layout managers so that your interfaces can adjust and look good on a variety of screen sizes and DPI. It's pretty simple once you wrap your brain around the idea. Another method of working with .ui files it to load them at runtime: https://srinikom.github.io/pyside-docs/PySide/QtUiTools/QUiLoader.html -- https://mail.python.org/mailman/listinfo/python-list
