What's the big problem? Someone needs to write an X backend for the android system and then you should be able to run most libraries (compiled for x86) in a chroot or something.
I have also posted an apk here (http://db.tt/UkFlvNAm) which has been tested on recent tablets (Galaxy Tab 2).
I have run Abiword on this in an ARM chroot, though on much slower hardware (a T-Mobile G2).
