Where I can find a good wordpress 开发者_StackOverflow中文版theme development tutorial? Something that is upgraded to the last versions of the WP API?

Thanks

From scratch.. Are you sure?. If you really want to start from scratch this will get you started: http://www.onextrapixel.com/2011/03/08/how-to-code-a-wordpress-3-0-theme-from-scratch/

But do you know a lot of handy WP theme frameworks exist? They will speed up development with at least 60%. Most of them can be used for personal and commercial perpose! One of my favourites is: http://wpstartbox.com/

For a comparison of different WP frameworks see: http://wpcandy.com/presents/wordpress-theme-framework-comparison
