the FOSS Qt version is fine.
Al,
I should also point out that great care must be taken when deciding to
use the FOSS licensed Qt. Their license expressly forbids any project
starting with the FOSS licensed Qt then later switching to the
Commercial license. Obviously, as WSJT-X is Open Source licensed, there
is no legal way to make it a commercial closed source application using
its sources. Just pointing out the details in case you might decide to
use Qt on other projects.
