Transfer the Functiongroup to Global Class

Hello ABAP-Objects gurus!

it is probably a very stuped question but any way....

Is it possible to convert the normal functiongroup to a global ABAP class?

I am a newbe in OOP but it seems to me that the function goups are similar to global ABAP-Class and the function-modules are like the methods of this class.

In order to use my funktion groups in WEB-Dynpro aplications I would like to create some classes from this groups and I am looking for some "wizards" for this perpouse.

I would be pleased for any help

Best regards
