How to convert server based desktop application to mobile (android and ios) application?

Hi all, I have created a server based desktop application. Now my client is asking for a mobile (android and ios) application.  And I want to publish that app in Mobile app store for Android and iOS mobiles. Is there any possibility to directly convert the desktop server based app to mobile app? Or do I need to build mobile pages separately for the mobile app. Please let me know how can I do this from starting. And also provide me if there is any videos contains this process for easy understanding purpose. Thanks in advance.
