Best desktop platform for CRUD on an online Rails web app?

There are so many choices, i need a win/mac application capable of sending info to a rails app开发者_C百科, i already have the rails app working on a server, so i just need basic crud activity via xml.

So what should you work this with , Realbasic, Java, Flex?

Thanks in advance.

If you feel like staying in Ruby then you could check out Monkeybars. I haven't done anything serious in it myself but it seems nice, except that the lack of new information on their site is a little discouraging.
