You had selected wxWidgets because of what?

Because of the neat grid class in wxWidgets. I did not find anything comparable in gtk.

Also, how long did it took (especially GUI part)?

Hard to say, because I work on that project on irregular times in my spare time. But the GUI part was not the big deal, because wxhaskell is such a handy library.
