Are there any docs available on how to create a custom wxpython installer for win32?
I want to package my application, python and wxpython all in one single installer for convenience. Since I want it to be upgradable by normal, official python and wxpython releases if possible, is there any documentation which tells me what registry settings I have to set and so on?
And for my own testing purposes: is there a way to have more than one version of python/wxpython installed at the same time?

Google for py2exe and Inno Setup. Py2exe packages up all your DLLs and your application files, and Inno Setup will create an installer. However, you will not be able to upgrade your customers' installs with official packages of python or wxpython. At least, not that I know about. You will need to build subsequent versions of your installer, which will package everything up again.
Yes, you can have more than one version of python installed. On Windows they install into different directories by default. You can also have different versions of wxPython installed, but from what I've seen, you can only have 1 version of wxPython installed per version of Python. You will not be able to mix wxPython versions within one Python install, as they will stomp on each other in your site-packages directory. Again, that I've seen, i could be wrong.

There is discussion , right now, on wxPython-dev about a system for allowing this. It's likely it will be there in the next release.

My problem is not how to create an installer for my application directly. I was a bit misleading when I talked about "application": my "program" is an plugin to an existing program: I wrote a DLL which makes it possible to use Python as a scripting language for Litestep (www.litestep.net, an alternative shell for windows). I need a fully capable python and wxpython (my gui lib of choice) since my users are supposed to write their own (wx)python scripts to extend their own litestep-themes.
But: the Litestep installer itself is only 3.5MB or so and people will balk at the prospect of downloading 19MB+ just to satisfy a new module for litestep itself when the average module is 50kB max. So one possibility I came up with is creating a "wxpython runtime package" like the JRE for Java: only the stuff needed to run scripts is included and nothing of the developer stuff. This would hopefully greatly reducing download size,especially when compressed with a much more efficient algorithm like bzip2 or7zip.

Since you say one can't install a "proper" custom (wx)python I will probably install my own private one under the Litestep directory. Is there a way to check for an already existing official python or wxpython on the system? If it satisfies the version requirements, I would want to use that instead of downloading my own version of only wxpython saving some traffic. If I know there is a proper wxpython, I might be able to fiddle with sys.path enough to make python happy

There have been discussions about this, and a little work so far. See the mail list archives and also http://wiki.wxpython.org/index.cgi/wxPRE

Python makes some registry settings when installed, but I don't think it requires them to be set. Although if you don't set them yourself you may want to rewrite the main Python startup module so it ignores any registry settings that are there already and then distribute this slightly customized Python.exe.
wxPython doesn't require any registry settings, although the installer makes a few just so it can keep track of things for uninstalls and reinstalls.
And for my own testing purposes: is there a way to have more than one version of python/wxpython installed at the same time?
A mechanism is being worked on. In the meantime you can move things around manually and then set PYTHONPATH or edit a .pth file to select which one will be imported.
