Take look at example: http://jsfiddle.net/AvpDk/

 normalState = new Object();
    normalState.stroke_width = null;
    normalState.stroke = null;
    normalState.fill = null;
    normalState.padding = null;
    normalState.r = null;

    hoverState = new Object();
    hoverState = normalState;
    hoverState.fill = 'red';

    pressedState = new Object();
    pressedState = normalState;

    var custombutton = chart.renderer.button('button', 74, 10, function(){
        alert('aaa');
    },null,hoverState,pressedState).add();
