Edit the information displayed by the Archive widget

Hi

I have been translating my website to several languages with qtranslate. I am using one page to display my posts and this page calls, using php, the widget Archive and Recent News.

My problem is translating the information displayed by the Archive widget. It displayes the months which contains posts. For example, if there are 2 posts from January and 1 from February, it will display the list January February as a link. I would like to know how to translate this information (month name) to the appropriate language because right now, it is only displayed in english, which is set as default language. How can I do this? I didn’t find the clue how to do it using qtranslate attribute and code, but i didn’t find it for the rest of the options. Is it possible? Thank you.
