You can use portia[1]. You can try out a hosted version at scrapinghub[2] or you can host your own. It's a web based spider creator like kimonolabs but the spiders it creates are just scrapy spiders. If you need to do something that the UI can't handle it's not a problem, you can extend it with a little python.
