Is it possible to add new control to Prism application without recompilation?

I have just one module in Prism application. Let this module have name "ModuleA" and application name is "CoolAppl". This application is cool and it works really okay in production. Once some guy would like toadd new button, for example "Delete Person", to this application "CoolAppl".

Is it possible to add new button "Delete Person" to application "CoolAppl"without recompilation?  

If it is possible, please, provide me direction where I should dig/search:).
