You can definitely get a garden going in your backyard. Key things to note - gardeners have a high churn rate & as Pathfinder pointed out, it can be tiresome but is an amazing experience once it's going. It is definitely worth your time to plan what you want out of your garden and what you need to put in place to get to your goals.
The biggest single issue with gardens is watering, followed closely by soil nutrition. I'd highly suggest looking at sub-irrigation systems inside of raised bed. These will make the effort and water usage much less than any other systems and greatly increase your success rate. Sub-irrigation will eliminate the need to weed (top layer of soil dries out which prevents unwanted germination). While you think about structures, consider placement based on how much sun your yard gets each season. SunCalc can be helpful when looking at lighting for different seasons.
Once you have the structures, the seasonal planning will be the next thing to figure out. Square Foot gardening can be helpful for quantity planning (and works well with sub-irrigation). The hardest thing to get right is exactly when to plant each type of plant. This varies from yard-to-yard and nurseries / plant supply businesses can give poor advice based on general area trends that are not relevant to you. Unfortunately, the only way to really know is to follow the best advice from gardeners near you and iterate until you find the timing and varieties that work best.
