Slice/Code in free time

[ultio]

Hi, I'm interested in picking up slicing and coding to do in my free time and was just curious what the best approach was to learn this skill. I don't actually want to design the layouts in photoshop but I'd rather learn how to cut them up and code them myself. I guess you could say as a hobby type thing with no intention of making money.

I found some tutorials but I was curious if learning the languages would be easier? I wouldn't mind spending time to actually learn everything, I'm in no rush.

So any suggestions on where to start and what I should be looking for would be very helpful. Thanks.
(I have photoshop and dreamweaver installed.)
