Converting Microsoft Access applications to JDE

In my company, employees are using number of standalone applications majorly developed in Microsoft Access and VB. As the applications are pure Windows form based application, they find advantage over JDE in fast typing, less number of clicks etc.
How can I merge the power of JDE and easiness of such applications together ? Using Power Forms ? Can you please give me some directions. I browsed lot of FAQs and documents on My Oracle site, those are really helpful.
