Go to the top floor of the Pokemon Center and talk to the farthest person on the right. The second option is the GTS. Click on it, save the game, and connect.
Go to Goldenrod then enter the GTS check the pokemons you want to trade with you have to have Wifi talk to the lady at the counter then connect to Wifi then there you go!
Any Pokemon that isn't an event Pokemon can be traded on the GTS.

You don't. All you have to do is talk to the lady on the upper right in any Pokemon center and select Global Trade and then either GTS or GTS Negotiations. You'll need a Wi-Fi Internet connection to connect.
yes
Set up NWFC. Set up Wi-Fi. Then, if you already have a badge, go to the GTS in Jublife City. Talk to the woman at the counter, then connect. Then you may either seek or offer Pokemon to trade.
Gts is in the top right hand of the pokemon center
if you mean the trading system for the game than no. the trading system only works on the ds.
go to Goldenrod city, the gts is in there.
No. So far the DS Emulator is still in development so as of yet, there is no possible way to connect to either the GTS or WiFi.
