BUILD ME A CUSTOM APP FOR XBMC/KODI

I need to make an app for Kodi that will install any build of kodi from a list, but keep some of the graphics here & there Custom so there is some level of Branding, plus add an extra menu to each build. 'Ares Wizard' & 'ChrisB Wizard' are the 2 closest things to what I want. Editing an existing app is acceptable. If you respond, if the first word of your response isn't 'KODI' then I'm deleting it before I read it. Also, if I have to educate you on what Kodi is, then please don't waste my time.
