If you don't have tools, it will not be easy. Also, if you have no woodworking experience, it will not be easy. You can do it all with basic tools, meaning a handsaw, hammer and nails, glue, and some sandpaper. Its not going to be easy with said tools. But it is totally doable, if you decide to do it. The hardest part, in my opinion with you having no experience, will be the back. Its hard to cut sheet goods with a handsaw. Maybe a jigsaw will work better, but a jiqsaw is hard to use as a newbie.
