Very kind of you. I've been building sigil for mac osx and it's easy to do as you have said.
I'll follow your advice and I'll study sigil code more deeply to get used to it before trying any improvement. I'm an experienced developer in java but I need some more training in C++ if I want to do something serious.

Sigil is cross-platform and written in C++, and very readable and the build is easy to do too. So someone well versed in C++ should have no trouble working with the Sigil codebase.
I think you will see many of epub3 features be supported in Sigil as QtWebKit support improves. Helping to move that forward is definitely something doable for a good developer and I am pretty sure that user_none (the developer/owner of Sigil) would accept patches that add features for some specific future version of Sigil.
That is of course his call.
But I do think the Sigil code base would be a big help in pushing your project forward. Talk to user_none and see what he thinks. Perhaps he can set up an experimental branch for you to add features too, that will eventually be incorporated back into the main line.
