The headboard, color scheme and lamps are the key to this design. Find versions of those and the rest should be fairly easy. Where would you normally shop for furniture? You should be able to take this photo into most big furniture outlets and they should be able to find you what they have that is similar. You're going to have to find a carpenter or get handy with a miter saw and a local woodworking/trim supply place to do the trim details. Find someone knowledgeable at Home Depot and they should be able to tell you how to do it and what you'll need. Ideally I think you would want the trim nailed with finish nails to the wall studs but you may be able to anchor them. I'm not sure about gluing, maybe someone else can chime in here.
