A japanese tutorial online that I could easily learn japanese from. With how to construct sentences and etc.?

I'm not entirely sure, as I didn't learn from the internet.
www.nihongoresources.com is a good resource, but you'll need to learn your kana ASAP.
www.hesjapanese.com has up some free beginner lessons (after that, you have to pay, I think).

I think ask.com has Japanese lessons, but you'll have to go search for them.

Yeah, that's all I've got. Sorry. =\
