I need to use remote push buttons for galil for the operators convenience like start, stop, spindle on, can any one guide me how to do this with Mach3 and Galil. 

In general, you would wire these buttons to an input.  And then you would use a Brain to take the appropriate action.  Have a look at the tutorials here: http://www.machsupport.com/videos/
