Filter / display posts by different language on homepage

My site has 2 languages: English and Polish. On Polish version I’d like to display recent posts written in Polish [http://redscouseworld.com/].
On English version [http://redscouseworld.com/en] I’d like to show recent posts written only in English.

I added following code:

<ul>
<?php $the_query = new WP_Query( 'showposts=4' ); ?>
<?php while ($the_query -> have_posts()) : $the_query -> the_post(); ?>
<li><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></li>
<li><?php the_excerpt(__('(more…)')); ?></li>
<?php endwhile;?>
</ul>

It displays four posts and some text. Could you tell me how to change the code to get what I’m looking for?

Thanks in advance!
