This is absolutely possible, moreover our friend Sitefinity Steve has already created a freebie widget collection
which includes that functionality. It can be installed on a locally deployed trial instance of Sitefinity, but not on a hosted sandbox trial if that's what you're asking for.
The page I gave you a link to contains installation and usage information. I hope that helps, Alyssa! Let me know if you need any further assistance!
