Developing for Nokia, which is the right technology?

I want to start development f开发者_开发技巧or Nokia devices. I've found the following SDK and I'm lost:

• Qt
• Web
• Java
• Symbian C++
• Adobe Flash
• Open C/C++

When I had a Nokia N70, I used Symbian C++, but now I have a Nokia E7-00 and I don't what SDK must I use.

I want to develop native apps (if it is possible) and sell them at Ovi Store.

Can you clarify my mess?

Ovi store is only available for Symbian phones so Qt / QML is probably the best choice
