You can use small Sprites with Bullet and Timer to get something like this.
Here is a quick example: https://www.dropbox.com/s/d8fmzoz2xehmc ... .capx?dl=1
Basically, just spawn multiple sprites with different angles at a point and start a timer, then when the timer is done set the angle towards the position of the UI element.
I've added a fade effect and a change of speed in the example, but you might want to play around with different effects to make it look good.
