hey sure can, its good to keep it going, if you're like me if I don't program for a while I tend to forget how to do things.. if you have a good grasp of the basics its not too hard to do plugins, loads of help online and from spigot forums, plus open source applications you can look at the code to see how things are done.
I reckon you can do a plugin in a coupe of weeks (depending on what you choose to do )
