Whatever software you decide to go with, there will be a learning curve. With some the curve is steeper than others, but on the long run you will be ahead.
The thing you must learn and understand to start with is basic photography, understanding exposure, depth of field, shutter speed, contrast, and not least what the camera sees compared to what your eyes see. Camera sensors do not catch and decode light signals the same way our eyes do. This is where the post-processing softwares come into play, making the scene captured rendered to your taste. And even the rendering can be different wether you plan on viewing the image on a screen (transparency) or on a print (reflection). So image editing softwares are just tools that you can use to improve the light caught by your camera and make it better looking on the screen or on paper.
LightRoom and Photoshop are not free, but there are so many tutorials that you can access that these are the two I recommend.
