Then TKL WordPress appliance should server your purposes. Once installed you can interact directly with your WordPress server via a web browser. FYI there is a VirtualBox tutorial here which should help you get started. Once you get to the screen you referred to in your initial post (the last screenshot in that tutorial) then you don't need to interact with your server via the VM window anymore, it's all done via your web browser (using the IP in the confconsole screen as I described above). Or with other tools (such as an SFTP client).
Once you get your appliance operational you should be able to access it via your web browser (on your host machine). I don't recall whether it's mentioned in the tutorial or not, but one gotcha is that by default VirtualBox sets networking to NAT, I suggest you change that to Bridged (Host only should work to, but you will only have access to/from your host machine).
As for configuring WordPress, I have no knowledge on how to do it, but TKL WordPress uses a standard WordPress install. As such, any instructions you find online should (hopefully) work (re setting language to German etc). If you keep in mind that TKL v11.x is Ubuntu 10.04/lucid server under the hood and that WordPress sits on top of Apache and MySQL, then you can use the vast resources of Google to help you out with finer details. Obviously the Ubuntu forums can be a useful place to find info, as well as WordPress community support would also be a good resource in this instance. And that is not to say don't post here, you are more than welcome to do that, but I have a very broad knowledge of Linux/Ubuntu/TKL but not a lot of depth (ie I know nothing about WordPress so won't be able to help you with specifics). There may be other users here who could help out, but maybe not...
Does that info help? Can you access your running appliance via your web browser? If not, post back but I probably need a few more details to be any further help to you.
If you just want WordPress
