Beginner Gardening: Landscaping computer software, 1 by brookig

Hello,
I am looking for some really good, simple landscaping computer software programs. We just built a home on 3 open acres with a stream on one side, and I have no idea where to begin, or how to arrange the plants by height, sun, water, color, bloom time etc. We are avid birdwatchers and have 2 children so we need to incorporate play areas and bird gardens. We would also need the software to design some hardscape as well.
I have heard that there are some programs that you can put a picture of your home in it and design it on the computer. I also saw some with 1,000's of different plants and specimens you can place in your beds. I am somewhat computer savvy, but not great! Hopefully I am not looking for the impossible software, VERY realistic, 3-D, or 4-D user friendly and cost effective! Any ideas would be WONDERFUL!! Here is just the back yard. The front yard is almost the same size..HELP!
Thank You For Your Help and Time
