Make my widget external in new window

Hi there, i need some pro help here!

I got a flash mp3 player in the sidebar of my blog, but every time i click on a new page the music stops. I’d like the visitors to be able to listen to music at the same time as they are surfing on my blog.

And the only solution i can figure out is to put this music player widget in an own window (When they click on a “open in a new window- link”) (wich is exacly the size of the widget)

So.. i need to know the codes to put one widget in an own window (own php document)… shit, i hope u guys know what i mean!

Regards
Kim
