If you're just looking for something fun and simple, Google SketchUp (http://sketchup.google.com) is a free download that lets you draw up any 3D object, including homes and interiors. This community-supported software has an ever-growing database of images (such as furniture) that you can incorporate into your sketch. There's also lots of help, including user guides, highly active help groups and video tutorials. When you're finished, you can even add your sketch to Google Earth and see how it fits into your neighborhood. While not as detailed and sophisticated as paid software, SketchUp is one way to play around without investing a lot of time or money. Google SketchUp is available for PC or Mac.
