As .deb packaging, it can be done manually. The question is, if You have code, that actually works in scratchbox/ Maemo emulator
I have created a deb for you using QT Creator with target Maemo of course. For just creating the package I used the build and deploy option, not the publish. I am not using ereswap, so I can't test it for you. But your program itself shows the four buttons Good luck with your development skills....
