Different Homepage

Hi,

I have a website https://www.islamicway.eu. I have created two subdomains https://en.islamicway.eu and https://lv.islamicway.eu. I find it managing two different subdomains easier than one with language translation plugins. I want to get rid of all content of https://www.islamicway.eu and just leave one main page that would have the same header (picuter) as the site in https://en.islamicway.eu and https://lv.islamicway.eu as they use identical themes. On https://www.islamicway.eu I want to have the header and after that two pictures with text English and Latvian with hyperlinks attached to them so that a user can navigate to his or her perfered language. Similar idea with Wikipedia.org as it also gives the choise of language on the main page and then it will direct you to a subdomain which corisponds to the language you have chosen.

How do I do that? Do I use the editor on the website itself or should I use a plugin?

Thanks!
