我想在linux中开发一个STMP/POP3客户端(仅限客户端)。我想使用数字证书加密数据(我将尝试提供端到端安全性)。我还想创建一个简单的界面(带有文本字段、发送按钮、收件箱等)。我的问题是:我应该用java(如果可能的话)还是C/C++(在这种情况下我必须使用一些工具来实现接口(interface)->QT)。你怎么认为？ 我的第二个问题:如果您有任何想法/建议或有用的链接(或任何对我有帮助的东西)，我将不胜感激。
最佳答案
关于你的第一个问题
should i do this in java(if it's possible) or C/C++
你可以使用任何你觉得舒服的语言，如果你想要我的建议，我建议你使用 java，因为使用 Swing 或 Javafx 创建图形界面非常容易，并且有很多库可以帮助实现你的目标。

这是一个简单的应用程序界面，可以从使用 JavaFx 创建的项目开始。
