It sounds like it got an infection, probably lacto if it's sour and gushing out of the bottle. That's a sanitation issue. What did you use for sanitizer, and what was your bottling procedure?
Beer doesn't take long to make, but I guess it depends on your perspective. It takes a couple hours on brewday, and then wait a couple of weeks. Then bottle (takes about an hour) and then wait a couple of weeks. So, active "beer time" is about 4-5 hours, and the waiting is the hardest part. If you have several batches going at one time, you'll have beer ready so the waiting is easier.
