Yes that is what I did too. If you now run the v1.3.8x version of Qt Creator you can design your forms, write your program, compile it and check it in Windows and then re-compile it for Maemo and test it live on the device over a USB connection all from within Qt creator as described in the original linked guide (using PCConnectivity). That allows you to give your program a quick test without having to package it and deploy it properly first.
