Ich habe das mit Xojo (vormals RealBasic) gemacht, das bisher nur 32bit konnte.
Zitat von Xojo:
Xojo and applications created with Xojo require these libraries:
GTK+ 2.20 (desktop)
glib 2.0 (web and console)
glibc-2.11
libstdc++.so.6.0.13
libwebkitgtk-1.0.0 or libgtkhtml (for HTMLViewer)
On 64-bit Linux distributions, you will need to ensure the appropriate 32-bit compatibility libraries are installed in order to run Xojo or applications built with Xojo. Note that glib 2.0 might not be included in 32-bit library packages, so be sure to check or install it manually.
