Hello,

The easiest way to do this is to use my Super Widget Package (available 
free from my site). After installing this, try:

Needs["SuperWidgetPackage`"];
k=0;
ff[x_]:=Print["k=",k];
{"Press for information",SuperWidgetButton[Null,"OK",ff]}//SuperGUIRun;

While[True,
   k++;
   ]

Each time you press the button, you will see the current value of k. Of 
course, you will have to kill the infinite loop in this trivial example 
by hand.
