You'll need a license if it's not open source as far as I can tell... I would lo...

I think you misread that. For any use, you need a licence, and the possible licences to choose from are 1. Commercial, or 2. Open source (GPL or LGPL).

You can make commercial software using one if the open source licenses. (Of course; otherwise it wouldn't be an open source licence.)

It's LGPL-compatible, though, isn't it? Can't you just wall off the Qt layer in a separate library, and release the source to that?

IANA lawyer, but my understanding is that you are correct. The LGPL doesn't force you to release the entire source, unless you are shipping a single static binary. If you dynamically link, you are good to go.

Perfect for me: develop the front end using Qt (on an OSS licence) and Go, which is just a dumb data rendering layer with caching, and keep all the actual business logic server-side. I'll happily open-source a "shell" :)
