Balcony Garden

Hi, I'm new to this forum and pretty new to gardening. I'm living in a flat at the moment which has a small balcony which is essentially an ugly grey box at the moment. I'm really hoping to get some flowers and plants out there to brighten it up plus some herbs and veggies as I really enjoy cooking and would like to try and produce some of my own food. So, basically my question is where is a good place to start? Obviously everything would be grown out of containers so I'm assuming that instantly rules out some plants. The walls of the balcony are railings and I'd love some kind of flowering climber preferably also with a strong fragrance (was thinking of honeysuckle or jasmine). Also, nothing too difficult to look afte as I'm a beginner and don't want to kill anything!!

Thanks for any help
