You may be right there: but with support for a couple of toolkits, you gain one
very important thing: improved independence regarding platforms and
libraries.

Right, too. Really, "targeting" Qt(4) is a perfectly reasonable
choice. Actually,
I have no clue what's the best option - but I fear committing to one particular
toolkit.
