want to buy Gold ETF and maybe shares

A belated reply:

Here is the gold ETF you mentioned:

and here is another new one - this time Kasikorn:

The trading arm of Bangkok Bank is called Bualuang Securities. They are not bad - see discussions about them in other recent discussion threads. As I mentioned in one of those threads, the value of having helpful staff in the nearest/local office can't be over-estimated, esp. when you are starting out. So first thing I would do is hunt out your nearest Bualuang office and go in and have a talk to them. Your local BKK Bank staff will be able to tell you where the nearest office is.
