Need a custom home page on Wordpress

Over time my blog became a site. I opened two sections more apart the blog which keeps running fine within the domain. First blog page is still the homepage; now I need to change that. My first guess is to add a custom page for homepage where user will be prompted to select one of the 3 sections of the site.

Is this goes to conflict with the permalinks that sustains the redirection from blogger? Do I need to add any redirection more?

Hello Miguel,
You can use any of the page template which you will be creating for the WordPress theme and you can assign that to page(where you want to show 3 sections). This will not affect the permalink redirection from blogger.
