news box

Hi everybody,
I’m using wordpress 3.2 and I need to add widget or something, in right sidebox with latest news. Maybe is there plugin for this, but I cant find…

Informations in green box are read from page with news, and I want to filter these news and show just first 3-4 news in that green box.

Page that contain news isnt category, just regular page with info that I need to filter and show in green box only.

Help!
