well you can use the free program called "gimp" if you need to do some graphics, it's an open source software that is known as the "free version of photoshop" It's interface and names of tools are a bit different than photoshop, but it will be good enough to do some web graphics.
here's the link
As for creating a website without the use of graphics is possible but in my opinion It would take a lot more care and time to do it, just because you don't have the graphics to help out on.
Sorry I don't have any samples for you.
