The "scrapbook" programs are very limited in their functionality. Most that start with them quickly graduate to regular graphics programs which offer tons more function and allow for more creativity.
You can use any graphics program that has layers, the three most popular for scrapbooking are Photoshop, Photoshop Elements and Paint Shop Pro. You can visit each of their websites for free trials and if you head to the link I gave above to digital sites, you will find many tutorials at several of them.
