Hello Sergio,
I think using Qt for this purpose involves buying a license from Troll Tech... have you looked at gtk ? (wich is in C and LGPL'ed) http://www.gtk.org

Thanks for your suggestion. You are right about the license, which is indeed very expensive. But I think that the company is willing to pay for it. I have no experience yet with either toolkits but a small study at the structure tips the balance to QT, at least for me. I am a naval architect (almost) not a programmer, and so are the people of the company, I think that if the code is well written in QT it is clearer and better reusable (e.g. inheritance) for them. But a final decision is not made yet. If other people have ideas about this, feel free to mail me, but maybe off this mailing list (??), since it has nothing to do with GPC.
Thanks, Menno
