Do you mean that you are first developing a regular
Java desktop application, using some desktop GUI library such as Swing or JavaFX, but your real goal is to make an Android app?
If you want to do this in Android, then making a GUI in Swing or JavaFX is not going to help you at all.
Java Android has its own GUI library, which is completely different from Swing or JavaFX. So you will not be able to use your desktop Java application on Android without rewriting a large part of it.

Ofcourse it's possible, you can program anything that is possible to program in software in Java.
