Ideas for simple 360 panorama simulation

I have to make some 360 panorama simulation for a school project. It should be some thing like this http://www.360gradpanorama.at/virtueller-rundgang/webdesign/rundgaenge/die_gruenanlage_vorm_riesenrad/die_gruenanlage_vorm_riesenrad.html , but of course much more simpler and without the vertical control option.
From the samples I’ve see it’s about editing of some panorama image. And as i don’t have any expеriеnce with this method decide to ask of some ideas and advices before the start.

Thanks
