Changing Language in Promotional Headline + Featured Content

It's me again :)) I've googled possible methods of doing this, however I'm concerned if I use their ..... methods of changing this I'll end up making more damage than good. I have two languages with each page having the option of two, however obviously there's some issues with doing this with the main page. I only want to be able to change the language for the promotional headline + featured contents section. It has been suggested to change some PHP or CSS codes, however with my complete lack of knowledge of such things I'm afraid of undoing all the 'good work' I've done. Any suggestions? Thanks do much!
