Unless you have separate tracks recorded for each instument and vocal then don't even bother trying.
It won't be quick as there is a significant learning curve in any audio editing system.
The step from sounding good to yourselves while you play to a good recorded sound is huge. Most beginners are disappointed with any attempt to record because they simply are not skilled nor tight enough as musicians and have not recorded in a suitable environment with suitable multitrack equipment using quality microphones and setups.
If you want to do this seriously then get the right gear and be patient enough to learn what you are doing both as musicians and as sound engineers.
I would recommend you download Reaper.
