Default Multiple categories Selection by Guests

Hi All,

I have a requirement and I tried to search Plugins Themes but not able to get any idea.

I have News Site [ redundant link removed ] where there are multiple Languages for which I created Categories. Menu is created at the top and I give those categories.

I want that when Guest open the site first time it give the option to select the categories(Language i.e. English and Hindi) and then front page give the news only from that language. Please note there is no registration option and it should give to guests and save in cookies.

There may be other interesting categories guests can select apart from language.

Please let me know how I can achive this.
