Asuming it works just like DevExpress reports then you must reference all DLL files required by for the Telerik reports. Then you can use them I your WiseJ project.
What I did to get the DevExpress reports working was to create an empty winforms project.
Add an empty DevExpress report so all references are added.
Then build the app
Then copy all the referenced DLLs to some folder.
Then open the WiseJ app and reference the DLL files that were copied.
Then copy the empty report files to the project and include them. This should add it as a report you can edit using visual studio designer.
This might be cumbersome but I managed to get it working this way.
Hope it will work for you and Telerik too.
