This will require a fairly good understanding of basic geometry.
Is your math level good enough to understand how this would
be modelled mathematically? If not you might find this quite
tough to get working. You can probably find sample code on
the net but if it doesn't work it will be hard to debug.

OTOH if your math skill is good then this shouldn't be too hard.
Can you tell us more about what you are using and what you
find difficult?

What are you drawing this on? Is it a GUI? If so, which one and
which widget?

Do you know how to make a ball move?  Forget the bouncing
just get them to move in a staight line for a fixed distance.

Then get them to stop when the meet the perimeter.

Then calculate the angles and set them in motion again.

Finally detect when they reach the hole.
