How would I use Fireworks CS4 to design my theme?

Hi, I’m working on developing my first theme. I’ve been doing a lot (and I mean a lot) of research as to the best way to go about doing this, and in doing so, I’ve run across several tutorials on how to design in Photoshop and translate that into your code… but I cannot seem to find any similar tutorials on how to implement Adobe’s Fireworks for this purpose. This is baffling to me, as Fireworks would be a far better choice for web design than Photoshop (after all, that’s what it was made for, right?), but I am totally new to the program and am unsure of whether or not the design/code process is the same for both programs. Any guidance on this would be greatly appreciated! (as would any guidance on creating my first theme, come to think of it)
