I think that sounds like a good idea (not doing a GUI just yet) but would recommend that perhaps you could do something pretty impure in terms of file or directory browsing. That wouldn't involve going beyond the standard libraries, but might give you some idea of the expressive power of the languages in terms of IO actions. I'm thinking something like a recursive grep, or wc -l... except preferably a bit more tailored to the sort of IO you'll have to do in your actual application. I guess the trick would be in finding something tough enough, since wc -l would be something like a two-liner...
