Well... after reading up on the wiki, and trying it out for myself it was not 
so hard to implement. Here is how I did it. in the startUp.js file , in the 
OnLoad() function near the bottom I added:

// extract the zoom-to x and y values from the cps args:
var coords = szCPS.split(',') ;
// 	setup framework
myXmlOverlay = new kaXmlOverlay( myKaMap, 250 );
var my_point = myXmlOverlay.addNewPoint('User Point', coords[0], coords[1]);
// 	create the symbol
var my_symbol = new kaXmlSymbol();
my_symbol.shape = 'square';
my_symbol.size = 10;
my_symbol.stroke = 2;
my_symbol.color = '#ff0000';
my_symbol.bcolor = '#ffffff';
// 	label the symbol
var my_label = new kaXmlLabel();
my_label.text = 'User Point';
my_label.color = '#ffffff';
my_label.h = 11;
