Nokia released the recent Beta of the Qt SDK and invites you to look at it and perhaps start to develop something, because it seems lot easier than you think it is :-)

"The Nokia Qt SDK v1.0 beta is the very first iteration of the Qt based cross-platform application development environment. We strongly encourage you to give us feedback of the quality, usability and feature set of the SDK. That helps us further developing the tool to the right direction."
