well heres somethin rather small for once.
if using mingw allready and in need of a simple ide/editor
ftp://90.184.233.166:21/geany.exe
gtk based and the gtk libraries are allready in it.
this build had some hacks by me to avoid having to define directory paths so it could find its dependencies and plugins, it now plugs right into the correct paths.
the exe is just a winrar sfx archive and only 27 mb's to install it just point it to your mingw directory and extract, make a shortcut somewhere to geany.exe and away you go.
the ide was primarily designed for gtk development but latest incarnation handles all kinds of sources (even latex).
it also has plugin support so more extensions can be easily added.
the included gtk runtime can be used for any gtk project considering you put the bin directory on path.
only a few plugins missing as theres some problems with them (gdb ya boo no debugger from inside the ide) and spellchecking (cant find its language files) so i left them out.
if you dont like the default theme use gtk2_prefs and change it

its in the bin folder.
