developing a PC-98 emulator

Hello fellow /prog/grammers.  I come with a question that I hope you will be able to answer or give me advice.  If not then at least make the troll posts obvious so that I don't waste time learning something useless. 

I want a PC-98 emulator, for Android.  I want to be able to play touhou(the first 5 games) on the go.  The thing is that even the emulator that exist for PC aren't that many and I think only one works good.

I currently only know Visual basic(a little since I learned it like 6 years ago and haven't used it in the 5 years after) and a little of python(learning it through google's online course).

The question is, can I make an emulator with that knowledge or is another language(other than python that is) better for the task?  And which?

Android run a modified Java VM, named Dalvik. So it's expected that most code which runs in a regular JVM can be converted to Dalvik's .dex class files.

Also, Android have this SL4A, which allow development in various scripting languages, Python included.

For the native counterpart, the NDK provides a cross-compiler and some libraries. Can't you download gcc sources and make your own for the same arm targets, and then link with android ndk's gcc?
