Ruby and GUIs
I finally threw in the towel on wxRuby for my little project. I ran into another roadblock where wxHtmlWindow was refusing to open external links, which pretty much killed me - every other problem, I'd been able to work around, but not this one. A shame. Maybe I can find some time to look at the wxWindows bindings and see if there's anything I can do, but I doubt that'll happen.
On a side note, I briefly looked at GTK, which seems to be better supported with Ruby. Unfortunately, it seems like the version of iconv.dll that ships with Rails conflicts with the version that GTK ships. I haven't had a chance to see if they can be made to co-exist, though my initial experiments weren't encouraging.
