thank you so much for the reply!... While waiting here for a reply, I send a mail to the wxpython mailing list, and got helped by robin dunn..
Now I feel more comfortable with the FC lib (wich is really great by the way). I've coded a lot since then, and now I don't have any troubles.. I feel like I can have a working program in 2 months!, so thank you for this lib, is really helping me a lot..
