reproductor en un onclick

[autonotel]

Creo que ya te entiendo:

Deberías poner el script dentro de una función:

Código:

<script type="text/javascript">
function repro(){ 
                            var gn = new SWFObject("http://source.netandino.com/player/player.swf","gnmpl","920","32","9"); 
                            gn.addParam("allowscriptaccess","always"); 
                            gn.addParam("allowfullscreen","true"); 
                            gn.addParam("wmode","opaque"); 
                            gn.addVariable("file","URL DE MI RADIO?type=.mp3"); 
                            gn.addVariable("duration","00"); 
                            gn.addVariable("provider","video"); 
                            gn.addVariable("bufferlength", "3"); 
                            gn.addVariable("autostart", "true"); 
                            gn.addVariable("skin", "http://source.netandino.com/theme/stylish_slim.swf"); 
                            gn.addVariable("quality","true"); 
                            gn.write("gnplayer"); 
}
                            </script>
<button onclick="repro()">Reproducir</button>

Sin olvidarte de poner el div anterior
