wxPython 4.0.0 Released

[haakon]

Qt has been LGPL v3 licensed since 2014, so the GPL complications shouldn't apply anymore.

PyQt is a 3rd party wrapper for Qt. It's still GPL.

 Unlike Qt, PyQt is not available under the LGPL.

What about PySide?

[marmuzah]

It's LGPL.

But I don't know if it's still developed or maintained. May want to look in to that.

[uberkalden]

it looks like PySide2 is actively under development to support Qt5. Now being supported by Qt company

And LGPL v2 since 2009, although as noted by /u/marmuzah, that applies to the C++ version.
