Hi, I am a little confused, which is easy to do! LOL
Do you want to know how to make the pointed lines around the circle?
Or the bubble effects on the circle?
For the line, make a preset shape with the star preset,(make sure that Anti-alias is checked) set it to have 25 points. Now copy this vector shape and paste as Vector Data or Control-G in PSPX.
You can grab the handle at either the start point of the first point or you can grab the twist/rotate/skew that starts from the center of the vector star. Now you can manipulate both layers in the vector groups and make this star shape almost identical to what you are showing in you post.
Then create a new raster layer above the vector layer and just place a circle of whatever means you have (tubes, brushes, whatever).
Now if you want to make that gradient type effect on your circle in the effects menu is something called Balls and Bubbles. Try that and play around with the settings until you come up with something close to what you have.
It also looks like they have added a white drop shadow underneath the circle area which is mainly visiable on the top left side of the circle.
