That's kind of a big question and not best discussed on IFDB. In brief, you'll probably want to go to either http://inform7.com and download a copy of Inform 7 -- or go to http://www.adrift.org.uk and download a copy of ADRIFT 4. Use one of these "authoring systems" to write your game. Get more help from http://www.intfiction.org/forum/ (the Interactive Fiction Community Forum).
