YOU. Don't give up! The beginnings are hard, but by trying to solve your problems yourself, you will learn a lot. Check for logs, or other hints the application can provide Debugging Crash Course. Try to search for examples in projects, or here in the Implementation Cookbook. Also, checking out the release notes can help. Maybe your problem is linked to the software components version.
Try to talk to your colleagues about the problem. You may be surprised, how many people have dealt with the same issue, and have already solved it.
