List of all features inside a buffer (Web map)

I have web map, created in the combination of: ExtJS 5, Openlayers 2, Geoext 2, and Geoserver.

My layers are in postgis linked to geoserver.

My scenario are 1 base map, an 10 normal layers. Actually i have a tree panel and i can view correct all the layers in the viewport.

The idea is the user click a point in the map and in someplace also input the meters to make a buffer of that point. Next i need to get a list of all the features of my 10 layers that are inside that buffer (ring).

How can I achieve this?
