    Re: Advanced UI Design

    I would recommend Qt.

    Widgets can be styled using a simple declarative language similar to CSS. This might make things easier if you're not a programmer.

    There is, but I don't know if they maintain python bindings (I don't think they do). There's no harm in asking either way :-)

    I believe ruby has more modules now.

    @O.P. I would recommend ruby over perl, purely for the nicer (my opinion) syntax. Check out BioRuby:
