look to see were the green stuff is coming from lol check the hoses and the pump itself and don't forget to check the heater hoses and core 100% correct. All a mechanic would do is look for the wet spot or the place that has dried crusty antifreeze. Plan on climbing underneath and getting a little dirty. If it's leaking at the radiator don't just put in a can of radiator stop-leak. That stuff will just cause you problems in the long run. If the radiator leaks, take it out and have a reputable radiator repair shop look at it. If you have green/brown streaks from the water pump it will HAVE to be replaced.

Anitifreeze leaking out black overflow hose on firewall of 1998 Pontiac grand am what can this problem be?

Honestly I think that Pontiac made the overflow reservoir too small. I have to add antifreeze to my GF's Grand Am once every couple months. If its a consistent problem where you're having to add antifreeze daily/weekly the car may be running too hot, and should probably be looked at by a mechanic.
