What about qconf? Project from Psi developers.
If you're interested in good example of using CMake with bitcoin sources you can look at sources of rpcminer. It have fork of Bitcoin with CMake.
Thanks, I'll take a look at that. As Qt Creator supports it it'd probably be the best bet. I really hate fooling around with m4 scripts as with autoconf, the only reason I mentioned that is because the mainline client wants to switch to it. Maybe we should do a post to the mailing list promoting cmake instead of automake?

I'm not so happy with the current address book window;

Especially the action buttons at the bottom of the window seem to be unintuitive to me; usually, buttons at the bottom apply to the entire dialog box, not items in a list.
Can someone more versed on sane UI design comment on this? Would it make more sense to put the buttons elsewhere?
