Hi Infernox and welcome to our forum!
You can cut and paste HTML from other products into InfoPath but not sure about how well it will work for Dreamweaver. Just try it and see. Images may require some special import but it's doable. You may have to polish up stuff a bit and if Dreamweaver has special stuff, it might not work well, but worth a try.
