GCF Goes Commercial
One of the nice things about Qt, in my opinion, is that they satisfy the needs not only of the F/OSS community, but also by the big dragons creating closed source software. They do this along the principle of "Quid Pro Quo", that is, if you make money without sharing your source, you need to pay. If you share your source we [Trolltech, which I'm not affiliated with] share ours for free.
Anyway, holders of commercial Qt licenses can do the same thing for their software. This is what VCreateLogic just did with their GCF framework. According to Prashanth, they sold 13 commercial licenses in one month - congratulations!
I got to know GCF as a judge in last year's QtCentre programming contest. It takes the abstraction one level beyond widgets and make it possible to build user interfaces using components. The cool thing is that you get a modern (albeit Microsoft-ish) look for free. And as GCF is dual licensed, you can try it out for your F/OSS project right now.

I thought there was a clause in the Commercial Qt licence that says you can't use GPL Qt to develop your software and then buy a Commercial Qt licence and release it closed-source using that. Is this not true?
Thats right. One will have to purchase license(s) of Qt before starting the development. This means that even before Line 0 of the code is written, the developer should buy Qt Licenses.
Thats what we did. We bought a license of Qt in November 2006 and over time we have bought 2 more. Having purchased commercial licenses of Qt; we can choose to license software written using it in GPL, Commercial or anything..
