Go to
www.webmonkey.com for good tutorials on two languages:
- PHP
- Coldfusion
Both of these languages are great. I am a coldfusion developer myself and have used both of these in the past. PHP is free and a strong language. The reason I put so much focus on Coldfusion myself is that though it is not free, it is probably the more powerful of the two with less typing for that power. However, to simply add a database to your intranet the higher ends of coldfusion or php aren't really necessary.
Hope this helps.
