Template frames

[Scale]

I'm not a bad coder although fairly new to lua,
Now i want to create a new addon now the coding im not worrying about.

It the frame to put it in im really not good at this,
So my question is are there simple template frames that i can find somewhere?

All i would need is a tooltip'ish frame (so just a square basicly ),
Which is semi transparent and can be moved by mouse.

Thanks for reading.
