LGPL License is sufficient or not for the below scenario

[khan]

I want to use qt-sdk-win-opensource-2010.01.exe file from the path http://get.qt.nokia.com/qtsdk/ . This is to write a small application using the QT Libraries (to open up the native file dialog window using “QFILEDIALOG CLASS”) in windows. Is license required or is it a freeware?

Qt (note the writing!) is not freeware. You have to choose a license: commercial, GPL or LGPL.

Thank you very much.
