Making GUI applications on Linux/Windows. What languages/tools to use? [closed]

Question

My student group and I are trying to continue working on a project we worked on this semester over the summer to become a professional, deployable app. We originally did it in Adobe AIR but it seems now that the computers this program will be running on will be very slow, maybe 600mhz and 128-256mb ram so flash just isn't going to cut it. It is basically a health diagnosis application that we will be shipping out to impoverished countries.

Now comes the real question. We are wondering what language to rebuild our application in. It has to have a good gui builder associated with it, like adobe flex/air gui builder or visual studio's gui builder but the application should run on linux primarily, and if it can run on windows thats just a plus. We are all students too without really any outside help so whatever we decide to do this in there must be ample documentation available when we hit problems.

Some things we have considered so far are using python and glade or c# and monodevelop, but again we really are not experts on any of this which is why I am asking for help as I would rather spend the time now choosing the right tools instead of wasting time down the line when we hit a roadblock.

Thanks in advance!

I see answers pushing wx and gtk, so I can't avoid pushing Qt, my favorite!-) With a major corporation standing behind it (Nokia), two excellent sets of Python bindings (PyQt and PySide), support for Python 3, the superb Qt Designer, great Mac and mobile support too... it's seriously hard to beat...!-)
