No mate you get a 60-day tourist visa from the nearest Thai Embassy to where you are and then you get a 30-day extension when your 60 days is nearly up for something around 2000 baht I think. You can try for a 90-day Non-Imm visa instead but others will be along shortly to tell ya how practical that is.

Oh and THERE IS NO SUCH THING as a 30-day visa on arrival if your passport is from a First World country. You get a 30-day visa exemption NOT THE SAME THING AT ALL.
