Build a VR pluginn for Panotour

I need a VR plugin for Panotour of for Krpano. Description: We have an online survey in store. User should be able to stare at same product, than pop up appears with two options > Buying and Not buying. User can select option A or B or close pop/up. All options selected must be saved somehow (post get URL or in log file). Unfinished example> [login to view URL] Note: Pop up should work in VR mode (as text or as graphics) and should give user chance to select option A or B or CLOSE. Selected option should be sent via post get URL or in log file.
