I agree with Jeffrey, this is better suited to Adobe Illustrator. Jeffrey's on the right track but it can be made a bit easier. In Illustrator, if you create the paths using any number of methods and convert them to Type on a Path objects, you can then choose Type > Threaded Text > Create to thread them all together. There's a trick though. In the stacking order, make sure that the top most element is at the bottom of the stacking order and then build up from there in the layers panel. It would be the reverse of what you visually want to appear but then they'll be threaded in the correct order. I know we're getting off topic here in an InDesign post so if this helps, I'll move it over to Illustrator.

There are some advantages to doing this Illustrator.

First, you can use the Polar Grid Tool to easily create the concentric circles. Note: the Polar Grid Tool is found under the Line Segment Tool.

Second, text can flow/thread from circle to circle in Illustrator. Note: this is a little tricky, and here are a few tips: Place returns in the text for each new line breaks. Select each and every circle with type on path tool to define that it will have text. Then flow text onto first circle. You can now continue to thread the remaining circles.
