People have enough faults and errors with soldering, so to hot glue it would be a nightmare. Plus, removing it after if you mess it up could be a big problem too.
Practice, practice, practice - get some old circuitry out of a junked stereo or something and try it - it's really not that hard - I started when I was about 14 (I'm now 33!!!
PS What are you trying to solder and where do you live ? (Uk etc?)
