Hi Wilkin,
You should be able to buy tubing in a local hardware store. The ERW
welding is very common and inexpensive. It's was around EUR0.40 a meter
the last time I checked for 25mm diameter steel tubing. I'd visit some
local stores first to ask about the steel tubing. Even a local plumber
may know where to get this tubing.
As for computer software to design a good chassis, well there is no
specialised cad software just for kart chassis that I'm aware of.
A 2 stroke motorcycle engine would be ideal.
Best of luck,
-steve
