Hm...I'm debating putting a bounty on getting this running natively on the maemo device line.
With Android's help it has brought things much closer.
And after looking deep into the guts of this...
there is good news and weird news...
libgtk1.2-dev and libglib1.2-dev are available for the older n800 and oldest 770 via "deb farm" catalog ..these are 2 dependencies which gtkgep relies on.
For the n900 gtkgep is being looked into by another member...but I won't mention by name directly without that person's "ok" .

For the n800 / n810 ...it is a hairier fur-ball to cough up.
Natively on gregale / chinook / diablo....
Installing libglib1.2-dev and libgtk1.2-dev directly ...even in using one of the earliest firmwares results in "incompatible armel". It just won't install...from turbo down to gregale.
Bits of libglib and libgtk are possible to install via programs like xmms which require them...but I don't know of any programs for n8x0 which specifically use the -dev variant of the needed libs...so a wee bit stuck there...(unless some program I didn't know about that has what is needed to install the -dev's is brought to my attention... that is)...
Non-natively ..
On Easy Debian...I'm still mucking about with that ...libglib1.2-dev and libgtk1.2-dev are available via lenny...however lenny has been put to pasture and archived ...the libs are still available ...albeit awkward to get at...sound via easy debian on n8x0 has been known to be "fun" to set up ..so in all ...it is likely quite possible to get gtkgep running via easy debian for the n8x0 ...but it sure isn't fun from where I'm standing....we'll see.

In all I'm thinking that perhaps KotCzarny may be the one of the best people who could suss out getting gtkgep (or some alteration of it) to work. (I'll have to pm him and ask...)
and perhaps rzr will have some ideas...he fiddled with ExEf back in the day....I'll have to sit down and write him as well ...

For the 770....well 770 users will be laughin' and dancin' over this....
technically it shouldn't be a problem to install the needed libs as long as the tablet firmware (meaning maemo 2) is old enough to accommodate them...
...once the gtkgep armel.deb is functional it should work pretty much seamlessly with the 770.

So yeah...
It'll be great to have this on the n900 and the 770...
and whether the program functions under gtk or gtk+ or python or whatever.. I don't care if it must be revamped to function ...
I want to see a functioning effects processor on the n8x0 devices.
So that leads me right back to statement number 1.
I 'm seriously considering a bounty for a fully functioning gtkgep (or an altered variant ) on our device line
