qt4, 435GB, I feel dizzy.
You are looking at 2 different things here:
- Blockchain size:
You have to have a copy of the Bitcoin blockchain. This is a design choice for Armory, it's a full wallet.
- Qt4:
That, along with py2, have been deprecated a long time ago, no modern OS support this stuff anymore. In the dev branch, there's a version that runs on py3/qt5 but it's not very user friendly. Assuming you do not want to download chain, you have 2 approaches to accessing your funds:
1. export the private keys to Electrum
2. build the dev branch from source. I'll then provide you with a remote supernode from which you can query your balance data. That will allow you to create transactions to move your funds out. This is a more involved process than the first option and will require more effort on your end than the first option. I'll try to handhold you along the way however. Up to you.
