No, not really. You can solve most problems with any number of mainstream languages with a few caveats. 1) The language has to run and be supported on the platform of choice (You probably can't use perl to write mobile apps nor are you likely to use ruby to build windows apps.). 2) If you have known speed, scale or other special requirements ie (you're probably not going to want to run a jvm language on embedded systems, and if you're running a system that's going to get billions of requests a second, you're probably going to want something that's multi-threaded or supports some type of concurrency)
