hi SAP SAP SAP
i forgot to mention, since your design comes in pdf form and you can easily implement it in webform (either offline or online form) then you dont really need to buy anything from market but if you mean something different to pdf form, i dont think SAP provide another solution other than pdf, even if you search for this phrase in google (SAP MOBILE FORMS) you gonna find SAP Interactive Forms by Adobe.
Look here:
Interactive PDF Forms on PDAs and Other Mobile Devices
and here:

anything i can help you with, just ask here,
Ali,
