I have gimp, and photoshop is too complicated for me. I was wondering if anyone can recommend some easy to use software to create professional looking photos like for family portraits. I was thinking about using a green screen maybe for backdrops. It can be freeware or paid software I just need some ideas of what is good and easy. I am a terrible artist and I hate using photo manipulation software.

 

Photoshop.

Figure out what you want to do, then look up tutorials on how to do it. Once you get accustomed to it, you'll be all set.
And don't be afraid to move the layout around a bit. I prefer a more 'classic' layout to my Photoshop:

Usually I keep the Animation window minimized, and the whole program maximized. Keeps everything I use frequently 'at hand' without clutter of stuff I don't use.
The "Painting" layout is similar to the one I use if you're interested.
