Finally managed to have a fast look at the sources
insert general rant against the evils of the wxwindows-site
sourceforge, rpm and the linux-dir-structure (what structure ?)
Ähm ...feeling better ;-)
You don't have to download the rpms if all you want is the sources. :-P
a) don't like the look (o.k.can probraly be changed).
It can sit on the native widget sets or toolkits. On Linux you can have wxX11 (which looks very plain), wxGTK (looks a bit dated now), wxGTK2 (much nicer, and totally configurable as you can configure GTK2's look). wxMSW looks like Windows. wxMUI would look like MUI and wxReaction would look like ReAction. See?
b) it's source is counting in MB ....
So?
c) I do remember all to well the mess that I saw in the OO.org or GTK sources when I had a closer look at that :-x
No one suggested it would be easy. I merely said it would be worth it.
Sure, it would be nice to have it, but wasting 2 or 3 good developers(*) just to get yet more ports 
No, you don't get it. The incoming ports would be nice, sure, but the main benefit would be in giving non-Amiga developers a reason to support the Amiga(*) and giving Amiga developers a chance to get their work to a wider audience.
(*) Those that can cope with big projects, which are few and far between in Amiga-land, and which are more or less all allready involved in one "big" project .....
Probably true, but that doesn't mean that they are all involved in a good development strategy. Not everyone is looking at the bigger picture or taking the long term future into account.
(*) I'm using "Amiga" in the generic sense rather than the trademarked one.
