how to add announcement list to a master page in SP 2010

I want to add an announcement list to my masterpage, so that these announcements are shown in all the pages in the sitecollection.

from googling i found out that we cannot add dynamic webparts to master page.

can this be achieved开发者_JAVA百科 programmatically or through powershell.

also i want to show the latest 3 announcements ( modified by date)

is it possible???

thanks in advance

Quite Simple really using the Content QUery WP. IN Presentation part of the Edit WP. Use the sort by Created in descending order and limit items to 3.
