Yeah of course but building an entire bike without knowing how to change a chain is a big step! Essentially you need a chain link extractor tool. You can either buy one, borrow one off someone on here or if you're in London you can pop over to Mycycle and they can lend, and most likely show you how to use one. Basically the aim is to push the pin out of a link, put the chain on with the desired amount of links and tension then just push the pin back in, but like I say, you'll most likely need an extractor.
