Cucumber isn't a tool exclusively for the Ruby world. The JVM is a very popular development platform and you can leverage your existing skills by automating your scenarios with Java, or its expressive by closely related brother Groovy.
This talk includes automating Cucumber scenarios with Groovy, from writing step definitions, working with tables, to exposing commonly used functionality with Cucumber's World mixin. Driving acceptance tests with Geb (a Groovy DSL for Selenium) will get you started with automating your scenarios through a browser.
