For your laptop, there was a project in August or September Silicon Chip magazine that does exactly what you want - go check it out.

You'll find this kit only operates up to 2.5A, and is not nearly enough to run most laptops which usually require a hearty 3-4A at 15-25Vdc. Jaycar does sell a little device that suits your purpose Stewart, just give me a PM about it 
As for stepping up a DC source, i think you have all covered the basics of it - it basically requires some switching circuits and a suitable transformer..... as you have mentioned... but there is a little more to it if you want to make the output decent.
But now if we wish to get into AC "inverting" from a DC source, this is where it gets tricky. You need crystal frequency locking, and some damn good switching circuits as well.... and thats just to get "sqaure wave AC". I am at a loss as to how pure sinewave inverters work!
