This is how the dialog usually comes up, with all fields filled in. For project languages that are not supported by MultiTerm, or that the tool is simply to stupid to recognise, the Source and Target fields may be empty. in that case, click the [...] buttons to fill them.

All fields except the description are mandatory. If any of them is missing, the OK button is disabled.

It's recommended to stick with the default location, so that the Clean function works, but you can select any folder here.

If you just want a basic termbase, you can click OK now. If you want to add fields, there is the obvious Add Fields button.
