Writing a demo for linux

Hi there /prog/,  I want to write an opengl demo for Linux using sepples, preferably using SDL or something cross-platformy so it will be easier to port to windows at a later point in time.  Can someone point me to one of those "talk to me like like I'm a 5 year old" resources to help me get opengl working with g++ on Ubuntu. 

Also, I'm used to using emacs for coding sepples on linux, but have mostly just used it for school projects just a few files.  This project will probably be a bit more complex though and cause my feeble mind more headaches without an IDE, so are there any good IDE's out there that work with emacs?

Thanks for the help /prog/

Effort isn't directly proportional to quality as proven by Microshaoft.
Both HMA and Pleasure of being ejaculated inside are pieces of mathematical beauty and they do not need processing to prove their exceptional value.
