Need Direction on how to Network?

I am a new Mac user and new to networking computers. I have a Mac in Texas and one in New York that I would like to network and control the one in New York remotely. Both Mac's are on wireless networks. I don't have any idea how or if this can be done but would appreciate someone pointing me towards any resources I can study or alternatively telling me no way. Thanks in advance for any comments. I have just jointed this forum and already picked up several tips that have been very helpful.

It's possible to do it. See the following guides on how to set it up.

Regards.
