Bed for the Cottage

I worked up plans to re-create Kate Winslet's bed from The Holiday. Here is a photo from the set, and the sketch I did in Adobe Illustrator:

I got a bunch of metal rings and wire from the jewelry-making aisle at the craft store, and some tiny little florets to cover the joins. If I can either glue or weld (right!) these bits together then a good coating of spray paint should give it the right look. Just curious, does anyone out there have any experience using one of those welding tools that instantly turns cold after you use it? I would only trust myself with one of those.
